69 Camaro inspection marks

[70 copo]

Kurt is correct.

I will expand a bit. Most of the colors were right vs left designations or QA/QC colors/marks applied by the manufacturing plants that were owned by GM (e.g. saganaw gear) and also paper tags/stickers to insure the correct part was installed to match the build manifest.

Other marks were simple assembly aids. A mark on top to designate "top or front" to prevent a worker from attempting the assembly task in the wrong orientation or non official build designation abbreviations mostly found on select front sheet metal components in the dog house build area. Another example was the radiator line where the metal designation tag would get dressed with crayon to highlight the letters on the tag. This was done to simply prevent post production rework and classed discrepancy on the line which could drag down the entire plant's quality score.

Finally class A defect marking: When a Class A discrepancy was encountered in production a 100% check was implemented as near as possible to the operation where the defect was first encountered. Typically the check was a mark or a daub of paint indicating that the assembly operation was performed correctly. When the defect was no longer present the requirement for the mark or daub was discontinued as the operation was then considered again "in control". (Ref: Echoes of Norwood Pages 127-128)

My 69Z, being a dry desert car had a bunch of these markings preserved.

When I took the suspension apart and cleaned everything I found pretty much all the same colors all over mine. White on the center link, pink and orange on most of the other parts. One spindle had so much orange on it, it looked like they just poured the can on it. Orange on the tie rods as well. It's also a factory manual steer car by the way.
