cowel installation shimming
« on: February 29, 2012, 02:03:30 AM »
Do you use the same body shims to shim the cowel as the fenders and rest of the body?   Thanks, Scoop

I just removed my cowl panel this weekend; I believe it is the first time it's ever been off.   There were standard body shim under two attaching screws (2 under 1, and 1 under the other).   Incidentally, I noted that the original body shims are slightly larger (maybe 1 or 2 mm) than the reproductions packaged by AMK in their fender bolt kit....

Yes, I have seen them, the same shims (approx. 1 1/8" square, variety of thicknesses, no "tail") as used on the upper rear fender attachment bolt at the base of the windshield post, used on the cowl grille panel - to cowl panel mounting points; the most I have seen are 2 per hole. as with all GM "shim cars", some cars had them, some more than others, and some did not. I love these cars, but they are certainly not a "Lexus" when it comes to fit & finish.
 The cars that I observed were apparently untouched cars, 67-69 Camaros and particularly 68-77 Novas. I have seen more Novas with the shims, and they are basically the same car with this in regards.
Regarding the headlamp mounting to core support shimming in your other posting, no, never seen this, but possible. I would check the mounting points on the core support for distortion; a length of 2 x 2 wood block and a properly administered hammer blow could also be what you need instead of a shim in this area.
Make sure you are installing the fender correctly; sometimes (ie: vertical rear upper fender-to-cowl attachment) the use of too many shims in one area can cause the need for otherwise unnecessary (cowl grille) ones elsewhere.
 
Hope this helps.

Yes, same shims that I'm aware of (same on our car) and they were phosphated.
