1969 Z21 Wheel Opening Moulding Bolts
« on: August 15, 2021, 10:55:31 PM »
The 1969 AIM for the RPO Z21 shows a change for the bolt ( screw assembly) mounting the moulding, inner fender, and fender together. The standard cars used a black bolt with floating washer, while the cars with the mouldings received a silver bolt with a serrated floating washer. When was the date change to the silver? Can't read the date in the AIM. thanks

It doesn't matter. The dates in the AIM are when the drawing got update, not when the change took place. The change may have been made weeks or even months before or after the date in the AIM.

Per the late John Hinckley:

Quote
A.I.M. dates are simply when the sheet was released from Drafting; the actual implementation date of a change could vary widely (in either direction) from the release date on the sheet. Implementation was tracked through the NPC (Notice of Production Change) system, and none of the NPC's have ever been made public - it was an internal system between Engineering, Purchasing, Production Control, and Manufacturing.

I know by April they were using the zinc plated bolt- I am planning on using the zinc ones on the L78 pacer I am currently doing built in late march unless I can determine it is 100% incorrect.
