69 Z/28 parts numbers

[66vettex2]

What is the best reference manual(s) for identifying all part numbers used in the 1969 Z/28? I'm starting a restoration project and would like to hear from others who have gone down this road.

The book by MacNeish.

Got the book but need more detail info similar to the judging manuals by the NCRS.

No such book exists...The book mentioned above is the best publication out there that is specific to the 69 Camaro Z/28, but of course, it can't contain everything there is to know. You're just gonna have to do your homework and compile your own resources... this site would be one good one!

66vettex2...You have a PM.

There are no so called "bibles" as to the correct restoration procedures. There are some very knoledegable people that do restoration work out there. They have based their knowledge by examining original cars to determine how things were done. The problem is, some of the people, who critique these cars, at some of the larger events, have no outlines to go by. I have been knocked for things that were clearly done just like they were done by GM at the factory....like smears of adheasive around the trunk weatherstrip, blobs of seam sealer at quarter panel seams, stamping marks where the quarter panels meet the rear body panel. These were intentionly done to duplicate the factory procedure. Other cars are allowed to get by with speaker holes cut out of the rear deck, and the transmission tunnel butchered out, but that's o.k. I almost got nailed for my driveshaft, because the one judge thought that the yokes should be in line, not offset. We showed him other cars that were like mine, one was a low mile original, untouched, unmolested big block, and the other was an original Yenko car. His response was that he would have to accept both, because his Yenko had the yokes in line !!! Maybe his is wrong ??? I really think a manual needs to be published, like the ones for the Corvettes. It would take alot of work, but I think that there are a lot of people that know these cars, that would be willing to contribute to this undertaking.

Without a manual the standards by which cars are judged to are subjective . Objective standards in the form of a judging/restorer manual will go a long way in providing the necessary standards. The Vintage group (survivor judging program) I am involved with has a accumulated data which should be used in suggested manual. The driveshaft issue mentioned by Frank, was resolved by using the Vintage/Survivor cars we were judging. The manual has been discussed and amongst the judges and we need to move this forward.

Best book on 69 Z28s has yet to be written. Its still in John Z's head since he was there when they went down the line!!!

Thanks for the insight into this matter and the PM's I received. I didn't realize that my question about a judging manual was such a hot topic. Not sure I have enough technical knowledge but would be willing to work on such a project.

Thanks again guys.

The 1969 Factory Assembly Instruction Manual (AIM) is full of part numbers...

[Mark_C]

Part numbers in the AIM hardly ever line up with the numbers actually stamped, cast or ink marked onto the actual part in the car. For example the centerlink part number in the AIM is a single engineering number for an assembly which includes the inner and outer tie rods, and the adjusting sleeves. These numbers are different than the Service part numbers in the parts manual (and on the box the parts come in). I know this is kind of a bogus example because there are no numbers on any of these parts, but you get the idea. You need to step down a level (or more) in the GM engineering program and find the engineering documents that governed the creation of each individual part, which isn't going to happen. Then of course GM had primary and alternate suppliers for each part which have their own individual markings. You have to look at the original cars to see the trends as to what parts are used when during the production year.
