1967 Dynacorn Fastback

In this build I will show the good and bad features of building a Dynacorn body.

My customer has wanted a Fastback Mustang for a long time but could not find a good body that did not require a lot of rust repair so he decided to buy a 1967 Dynacorn body. He started calling around and could not find a body back in January. He called Dynacorn and they told him they had no idea when they would get one in. He was getting discouraged and had to go back to work where he works 10 weeks and than is off 10 weeks. When he got back in town he started checking around and still nobody had one. He found a project that was never started that came with a lot of extra parts so he bought it.



Some of the good points are the shock tower braces, extra welding in the engine compartment and a lot more spot welds and the export brace





Another good feature is the one piece seat riser.



I have never seen an after market valance fit this good but it is bolted together instead of screws.

Hey, I really like that one-piece seat stand!

Thanks for sharing this, Rusty. I look forward to following the build. Now, to get to the elephant in the room, how do you plan on registering the car? Must you register it as a kit car? Or, in your state, can you use the VIN from a production Mustang?

That's interesting that your customer could not find a Dynacorn body. I assumed they were cranking them out right and left. But perhaps they had a short production run then stopped. (??)

It will not have a Vin from a Mustang. The only used Mustang parts he has are front seats and quarter louvers.

There were no 1967 or 1968 bodies available. He also thought about a 1965 Fastback but again they had no idea when they would be available.

You always do quality work so I'm anxious to see how you handle some of the nuances that a Dynacorn body presents. I'm sure it won't be anything less than spectacular once you're done with it.

We have not had the time to work on this yet but have an issue with the door gaps. This is what we found so far:

The hood bumper brackets are not straight





Dynacorn does not spot weld the quarters they are plug welded and than they ground the welds to much.

Hi,
That's a weird occurrence with the hood bumper brackets?
I like many others, thought you you made a call, laid down your dough, placed and order and took possession soon there after. Do they build on-order? Anyone?

I always figured they made bodies in batches. Would imagine there is a bit of tooling involved to make them and they'd not want to re-setup things on a per order basis. I'd actually love to build a car up from one but roughly ran the numbers years ago and seemed the costs to do so far exceeded starting with something more complete and reworking that into what I'd want.

This could be the thread of the century. Your going to miss all the rust you usually deal with

I recently replaced my core support with a dynacore one and my hood bumper brackets are not straight either. I need to drill them out and re-weld them on straight. Seriously, how hard is it to make this stuff correct? W T F...

The door and trunk bolts are metric



We thought at first they had metric threads but they are the same as all Mustangs so I changed them. Notice there is no ecoat under the fender brace. We will be sanding the complete body and spraying 2 coats of SPI epoxy.

So they are metric or not? I confused!

I would be interested after you finish to get your opinion to see if it was worth it to start with the rust free body or buy a good used one and repair the typical rust.

I know each original body is different, but I pretty much assumed that if the Dynacorn body was pretty much ready to go (with only minor stuff) it would be a much better way to proceed.

Rusty, I know this may be a bit out there, but after seeing the work that goes on in your shop and the speed with which it gets done, along with your attention to detail, have you considered contacting Dynacorn about possibly assembling the bodies in your shop?

If there are no bodies to be had it can mean two things, either they are selling faster than anticipated, and assembly can't keep up; or they are not, and the whole body program is going down the drain.

The biggest expenditure for a venture like this would be the body buck or jig, and subassembly jigs. Somehow, I think you'd do a better job of that than is presently being done.

Just a though.

Rusty,
For all of the hype that precluded these bodies, you'd a thunk, these issues would be non-existent. The worst of which, is those bumper brackets. Be nice to keep track of the "mysteries" as they unfold in your restoration.
Has anyone tried to contact them on this, do you know? That metric thing is crazy, as well as, the omitted e-coat.
Thanks for your comments!
