1st Gen Body Shims - Shape vs. Part Number
« on: February 11, 2022, 02:43:28 AM »
Every winter I pick an area on my Camaro to restore (again since my car was restored just over 22 years ago), or make technical corrections.  This winter's project to correct the front end sheet metal shims, the RS head light housing shims, plus a few other areas on my '69 RS Z28.  I reviewed several post on CRG where folks have posted pictures of the original shims from their cars.

Question 1: Referring to the following pages in the Assembly Instruction Manual (AIM),  it list the same shim part number 3711834 for the following locations to align the front fender sheet metal:

AIM page 138, UPC Sect. 11/13 A2 fender shims = #3711834 for top and front position on fender attachment to the body.

AIM page 146, UPC Sect. 11-13 B3 fender shims = #3711834 for the lower attachment of fender and fender skirt to body.

For the RS headlight housing: refer to AIM page 459, Sect. Z22 B3 RS headlight housing shims = #3903452

The picture attached I borrowed from bcmiller who posted a picture of an assortment of original shims back in April 2013.  I have a few shims the same as the square corner smaller "horse shoe" shim in his picture.  I wonder where this shim was used?  Is this shim #3711834 called out in the AIM use in various locations?  What about the rounded corner shim that is close in size?

The logical place for the wider (larger shim) would be the lower rear corner fender position shown in the AIM page 459; however, I could be wrong.

Question 2:  For the RS headlight housing, it appears both shims with the rounded handle have been found as originally used for this application.  Perhaps there were two supplier for the same application?

There is a supplier Inline Tube on eBay that advertises he sells the technically correct shims that are phosphate plated. They appear similar to those in bcmiler's picture but not exact.  Does anyone have experience with them?

Can any one confirm which fender shims were used in what location, or are they all commonly used in all different locations?

Thanks!
Dave

To follow up on this topic, I took a picture of two different shape body shims I had left over from when I restored my '69.  I also included a couple pictures from the AIM showing where shim #3711834 is used in all the front fender attachment point.  I believe the square 1-1/4" x 1-1/4" x 1/8" thick with 3/8" slot shim is the #3711834 shown in the AIM.  This square shim looks like the shims I have seen recently from an original '69 Z28 undergoing restoration.

My question concerns the rectangular shim measuring 1-1/2" x 1-1/4" x 1/8" thick with 1/2" slot shown.  Does anyone have a survivor 1st Gen (or a '69 with its original shims) that uses this style rectangular shim, and where is it located?  Its been 27 years since I restored my '69 Z28 and I don't recall where I pulled these shims from.  I think it was located in one of the two lower fender attachment points between the door and front tire.  This is a logical spot for this shape shim as the slot in the fender at those two points is about 3/4" wide.


Thanks in advance for your input (and photos please)!
