II have a 1966 Mustang converted from I6 to 5.0. I replaced the entire front suspension with OEM parts from Laurel Mountain Mustang. I installed the Grenada disc swap from DiscBrakeSwap.com. As it sits right now I have 7/8" shimms in the upper control arms and still have a negative camber of 5 degrees. I need to add an additional 3/8" of shims to get me between 0-1 degree of camber but no more room on the UCA bolt. This seems dangerous as hell and dont feel comfortable running it this way. I have talked to both suppliers and verified measurements on the upper CA to be 9 3/4" from pivot to ball joint and the lower CA to be 14" or 13 7/8" to be exact from pivot to zirk fitting at the ball joint. The next thought was that my shock towers were sagging but after diassembly of the front end and multiple measurements that is not the case. The factory specs say you shouldn't shimm more than a 1/4" max. Everyone seems to be stumped. They also said it may be my steering linkage from the I6 since I have yet to convert it but it isn't hooked up right now and still have the problem. Once I figure out how to post pictures I'll get one up. I am open to ideas. Please HELP!
steering linkage doesnt have anything to do with camber. it sounds like the shock towers are sagging. i highly recomend you purchase a scott drake export brace and monte carlo bar. if it dont fit which i bet it dont the shock towers will need to be pulled out. it doesnt take much of a sag to throw the camber way off.
Get us a picture of your shock towers from the inside. If they are really allowing -5 degrees of camber, the shock towers could have pulled all the spot welds and be resting up against your headers. I recently had my shock towers fully welded as insurance against this ever happening (It also stiffens up the chassis). Unfortunately only adding an export brace or Monte-Carlo bar isn't going to do anything if your towers have started to separate. Be careful though, as the guy I had to it did it too far and I lost a bit of negative camber. Have a look at this article:
IFFF the center-to-center distance between the two bolt-holes that the left/right lower control arms bolt to, is correct per Ford's dimension....
And IFFF the inside-to-inside dimension across the engine compartment, to the surfaces where the upper control arm nuts tighten against is correct to Ford's dimension....
You have installed some incorrect parts or have something installed backwards, although I can't think of anything that could be backwards?? Maybe the upper ball joints rotated 180? Seems like their centerline is NOT in the middle of the rivet holes?
Did YOU remove the old stuff or did someone else?
Was it right with that stuff on?
Any shock tower/fender-apron/core-support/frame rails been replaced?
If you still have your old suspension parts I would compare them to your new ones. what spindles are you using? if your shock towers are not sagging and usually they are ok on 6cyl cars then either your upper control arm is to short or your lower arm is to long. Or you have a problem with your spindle. Are both sides like this?
I think Cmefly is right. I'd get a measurment from lower B/J to inner pivot point and compare to a known 66 LCA. I wouldn't put it past Laurel Mountain to ship you 68+ LCAs.
It could be shock tower sag, but that's a lot for a 6 cylinder car. Just the same, you shouls install the monte carlo/export brace as Super Shifter suggested.

I have exchanged several emails and a phone call with the OP and I am not stumped. I expressed my belief that he has 68 LCAs on the car. He states that the dimension from center of ball joint to the center of bushing is around 14". I measured this dimension on 2 of my 65-66 Mustangs at about 13".
I have confirmed that he has the correct part number for the CSRP 65-66 type spindle.
Ok let's make sure everyone is measuring from the same place. Just checked the set I removed from my GT coupe and I got the same measurement as OP measuring on the bottom side to the zirk fitting. If I flip them over and measure the top side to the bolt from the ball joint it's more like 13". I haven't measured the UCA. I also measured the new set I have still in box and have the same measurement.

68-70 lca will not fit the 65-66 strut rod. i have ben told that 67 lca will fit but its about 2.5" longer and would really kick the bottom of the tire out.
He said he already has 7/8" of shims installed. Crazy to still have negative camber. It must have the wrong lower control arms.I would like to see some pics with the tire off. DIEHARD is your camber the same on both sides? And how was it before changing the suspension?
