I like to take pictures of my cars and what I do to them, so I plan on using this as my build thread. First things first though, I am not a mechanic. I work on my cars for fun and therapy. I screw things up sometimes, so bear with me. If I do something stupid, be gentle.

Here is the car the day I got it:







I bought it from a friend of the family for an amazing price. I bugged the owner for years about it, persistence paid off. He had it restored around 6 years ago, and it was rarely driven after that. It sat for a long time, so it needs some love. The tires would not even try to inflate when air was put to them, there were very weather cracked. New ones were put on immediately so that I could roll this thing around.



The next thing I did was try and start it. I changed the oil, drained the gas tank, and topped off the coolant. I plopped a new battery in, and she started right up. I was amazed. The previous owner had the engine re-built when it was painted, but I was still surprised. I rolled it out and washed it.

I have only found a few small rust places. The very front of the drivers door has a small bubble under the paint, but not popped through yet. The top of the inner fender had a bubble, and this:





I hear battery tray rot is common. I bought a replacement tray and inner fender apron from Mustangs Unlimited and went to town. I had a 280z in the past that I learned to weld on, this was a fairly easy job. Fender off:

Now for my recent project. Disc brakes up front. The stock drums up front were frozen solid, and instead of putting money into rebuilding them, I decided to go straight for discs. I had just spent money on tires, and I wanted to keep the stock wheels. Since I have the 4-lug set up, the most affordable option seemed to be the Scarebird kit, or as its called in my house, the "none of this #$%# fits like its supposed to" kit.

After a few weeks, I had assembled everything I needed (or so I thought) for the kit:







OK, this is what we are looking at:
Scarebird brackets and rotor spacer rings.
New bearings and wheel seals
Nissan Stanza rotors (that needed the stud holes enlarged)
Chevy Cavalier calipers
New studs (that needed their threads chased)
Banjo bolts
74 Maverick disc/drum master cylinder

This should be easy, right?

First, let me say the Scarebird brackets are very well made, and worth the money. The rings that center the rotors fit perfectly, the brackets fit well but needed a slight modification to work for me.

Here are the stock drums



Taken off, the drum and the bare spindle:





Getting the frozen drums apart to get the hubs out was a struggle. I ended up busting out the grinder, as shown:



The hubs need to be modified a bit to fit inside the rotors. Here is a stock hub, and one after I cut the ears down a little:





Then I mounted the brackets and the hubs onto the spindles with the new bearings and stuff. Everything went on great, and I painted the brackets silver.

So far so good! Then I went to put the calipers on, they did not fit. After some head scratching and measuring, I decided that cutting the back side of the nuts on the Scarebird bracket would get me the clearance I needed. Hopefully this pic will show you where I did this.



They fit! Check out the bling on those gold calipers. Oh, they fit just fine behind my 68 steel wheels:

Next up are the brake lines. Scarebird recommends 1980 cadillac eldorado lines, so that's what I got. I thought they would be a bolt in item, silly me. The threads on the car side did not match the Mustang brake lines, and required adapters. I found the ones I needed at Ace Hardware of all places.

Here is a cool shot of the car on stands with its gold calipers hanging out for everyone to see:



So, the next part of the project is the master cylinder. I am replacing the stock unit with one from a 74 Maverick with front discs and rear drums. For some reason I thought this would be a bolt in item.



After some research, I think I need an adjustable proportioning valve for the rear, and new lines from the MC to the distribution block. That is where I am at now, stay tuned.

I ended up having to put in a proportioning valve for my rear brakes, I will snap some pics of it when I get a chance.

My next project was the ignition. I wanted to get rid of the points style ignition, and upgrade to something I could use when I put my V8 in. I decided a duraspark 2 setup was the best option for me.

I bought all the parts I needed from autozone/schucks/napa for less than 200 bucks. Just ask for parts from a 1980 Ford Fairmont.

Here is my new Accel coil and ignition control box mounted to the drivers inner fender:



On problem I ran into with the swap was with the larger distributor cap. It interferes with the power steering bracket. I cut a chunk out of the bracket to make room:

Before:



After:





Here are some shots of everything wired up. I tapped into the switched 12v post on the starter solenoid for the control box, and used the stock 12v lead for the coil. Those are the only two places the system ties into the stock wiring.







Believe it or not, it started. I need to set the timing, but I know it works. :pirate:

Car runs like a champion with the new ignition. My next project was to install a tach to keep a better eye on the engine. I found this one at O'reily's, its not the Sunpro that a lot of people use, but I like it and it fit well:



Here is a shot of the stock dash and gauge cluster:



Out of the car on the bench:



Here is the back with the new gauge in the middle slot:



Here it is from the front. I like it, the gauge fits in well and does not stick out like a sore thumb.

I got a wild hair this weekend and decided to lower the stang. Some parts were easier than I thought they would be, some were harder. First order of business, the rear shocks. They rode really rough, now I know why. They were the stock shocks that came on the car in 1968. Think about that, its crazy.



I measured from the ground to the wheel well lip before I did anything, it was a little over 26 inches.





Here are the blocks I got for the rear, 30 bucks at Autozone. They are the 2" model. Just a couple of notes here: The shock bracket holes need to be enlarged for the thicker u-bolts, and the u-bolts need to be trimmed down. Other than that, they went on great. I also got some cheapo shocks, way better than before.

I did'nt take many pics of what I did up front. Its the basic Shelby upper arm drop and coil cut. This was my first time doing either, it was scary but what the heck. Here is the upper arm mounted, with the stock holes peeking out.



Here are the coils. After some research, I decided to cut off one whole coil. It turned out to be perfect.



I slapped it all back together, held my breath, and put it back on the ground. I re-measured the well, I managed to drop it 2" all around first try. Let me say, 2" makes a HUGE difference.

Now I need to get an alignment.

I copied this over from my stereo thread, but will put it here to keep things in one place.

The time has come for some tunes in the Mustang. I took a lot of ideas from Weare138's convertible install. My goals were to have a decent sounding system with a little bass, be inexpensive, and for it to be as stealthy as possible. This might get a little wordy, I will try to keep it short but provide info too.

First, the front speakers. I could have got kick panels like most people do, but I don't like the looks of them, and they seem to stick out into the foot area too far. So I busted out the tape measure, and the first thing I decided was the foot pump for the windshield had to go (not hooked up anyway) and the headlight button had to move.



Here is the pedal gone and the button down 3" or so:



The problem with removing the pedal in the 68 is that it affects your wipers. They will not return to the park position when you turn them off. This can be fixed my putting a jumper wire in between the two black wires that go to the plug:



Next I started work on my front speaker boxes. I wanted them tucked way up on the floorboards. I went with 5.25" components from Lanzar. They were around 60 bucks shipped from Amazon. I know Lanzar isn't what it used to be, but I still like the brand.





I don't have a picture of the grill that came with the Lanzars, but trust me they are horrid. I went to the local stereo place and asked if they had and take-off grills that were nice and basic. I scored a set of JBL grills for 10 bucks. They are a little bog, so one edge had to be cut for the boxes to fit where I wanted them. Here they are carpeted and in place. Neither is in the way of anything (that would be different if this was a manual car) and the wife's short legs can't reach to bash the passenger side one in.

I planned from the beginning to run this all off my Ipod. So I put the component crossovers where the radio normally goes.







Like Weare138 did, I am using the JL Audio line control. I bought a cable that goes from the IPod dock connector to RCA, then from that to the JL piece, then back to the amp. The cable also charges the Ipod, which is nice.



I then got a cheapo plastic center console to mount my Ipod and knobs to. My pod had velcro on the back, and sticks to that carpeted square in the picture. The top knob is volume, the bottom is the bass boost from the amp.

Now my attention was turned toward the rear of the car. I was set on having the subs be "invisible", so I wanted to fire them forward ad the box to be as skinny as possible. One thing I found out, there is not a lot of room back there. I was going to use a single 12, but that went out the window as soon as I opened my tape measure.

Here is what I started with:



Here is the base of my box, it is built his way to provide a flat platform that spans over the shock access area, which is very lumpy and uneven.





This is the box I built. It looks basic, but took a lot of time. I had to make it the right internal volume for the subs (1 cu ft) plus be able to install it in the car after it was built. Sounds easy, it was not.



Here it is with the holes cut out. Two 8" subs are just the ticket for this area.



These are the subs I decided on. Apex Jr Super 8's. I did a lot of research, and these sounded like the best bang for the buck. 70 dollars for two plus shipping. Now that they are in, I am not disappointed.





Here is one installed, with the metal divider cut. Because the back seat is mostly hollow, there is no interference with the subs, which is good because these little monsters MOVE.



Here is the back of the box... for now. The platform is only 10" deep, and the box is only 7" deep. This let me mount the amp to the box, but still keep it right at the edge where the trunk floor angles up. This will be covered by a flat black carpeted panel, my hope is that its tucked far enough back that it will look like nothings there on first glance. I will update when this gets done.

This set up sounded pretty good, but not quite the low end I was hoping for. So, I decided to port the sub box. In order to do this, I needed to increase the boxes internal volume from 1 cubic foot to 1.4 cubic foot. With two 2" diameter, 8 inch long ports, the box would be tuned to roughly 38 hz. Here is a before shot of the rear of the box:



Then I made this extension piece that looks like a drawer.



I cut a large hole in the back of the box, then bolted / liquid nailed the drawer into place. It is air tight, and gave me the volume I needed.





Here are where the ports exit. They go into 90 degree fitting inside the box, I had to do this to get the 8" length I needed. they aren't the prettiest, but the seat covers this all the time. Which is good, because 2" diameter ports turned out to be a little too small. On low bass notes, I get some port noise. The seat muffles it mostly, but I can still hear it. I'm picky about that sort of thing though.
