I am trying to figure out the correct bolts for some of the applications on my car..

I have the assembly manual..

and it lists individual bolts as part numbers..

is there a resource anywhere that would help me figure out what these part numbers are in human terms.

example.. the bolts that connect the front frame extensions to the frame are part numbers 9419101 and 3926435..

I want to know they are.. something like 9419101 = 1/2" x 1"long NC

I wonder if you could get that breakdown from a vendor that sells bolt kits.

Paragon printed a laminated color poster which showed most of the bolts and fasteners, what they looked like, markings, etc., for a typical vette. They were giving them away at various car shows. Contact them or see if you have a local rep in your area.

I'm sure that each number in the sequence stands for something. Some of our part numbers were created with that in mind. I wonder if a GM dealer could or would have something that would tell you that information.

ive emailed docrebuild about it

well see if he has an answer..

A GM part number reference may turn out to be more than cumbersome. Virtually all the part numbers have either been discontinued or superceded a couple of times. Their descriptions are vague at best, ie; bolt,carrier ass'y.
The doc or that chart sounds like your best bet.

Part number 3926435 there should be 2 of them. In 1969 their cost was $.18 each and the defination was the following: front bumper frame extentions (1/2" - 13 x 1.

If this sounds correct to you, I got my hands on a Chevorolet 1953-76 Corvette Parts Catalog. I think this has everything you are looking for. I will check on your other part number.

actually I have a huge laundry list of stuff

where did you get this book??

I think it would be easier if I just bought one..

thanks

doc's response

Several books help, but none are complete. GM P&A #30 is the Corvette part book, it only lists only some, however the section containing illustrations does have sizes - but not corresponding GM part numbers in those illustrations. An exploded view of the dash would ID many screws by size and location, but not part number. So those illustrations are helpful, but you must manually correlate them to the Assembly Instruction Manual part numbers. The GM standard parts book lists hardware, fasteners, fittings, clips, etc - i.e. standard parts or nuts, bolts, etc. The part numbers in these books (issued annually) do show a part number and a corresponding size - but - but - an extremely small number of those part numbers are the same as shown in an Assembly Instruction Manual. A third book, called the GM Part History lists part numbers that are no longer available as new - with has their disposition. This may merely say part number 123456 was discontinued on 11/97 or it may provide a reference to an acceptable substitute. Often it may say: Part number 1234567 use 1 piece 23456 and 1 piece 34567. That in itself is no help. One must now take that new part number and look it up in the Standard Parts Book to see if it is listed. If the original part was a hex cap screw with a captive lock washer (i.e. not a loose removable lock washer) it may provide 2 new referenced part numbers - one for the hex cap screw and one for the lock washer. The separate screw and washer will work and are not detectable when installed, however originally it was an assembled fastener to speed production. Another source is the actual Corvette, if the hardware is intact, however as you know that is not the case. Honestly it's a long hum drum process of checking a numbers, which leads to another number and sometimes a third number and then manually searching through all the listings of the probable sizes in the Standard Parts Books. They come out annually also, and change. So part numbers often get superceded several times. When I searched, the first thing I would do is see if the part number changed. If it did, then check the new part number to se if it also was changed. When I found a part number was active (i.e. listed in the current GM Parts and Accessories Price Manual) then I would look in the corresponding Standard Parts Book. It ain't easy. I started when C3's were still relatively new and honestly my collection of personal Assembly Instruction Manual are literally tattered and torn but highly annotated with sizes next to most fastener part numbers. I'm not exaggerating the least. (In a few years, I'll put them on ebay or donate them to the Smithsonian Museum for - fuel. :D)

I actually just lucked upon this copy at the Turkey Run in Daytona a couple of years ago. I have no idea where you could actually find a copy. I made a copy of the one I bought because the paper was so thin and old. The print is mostly in good shape. I would glad to check into Kinkos if you want and see what it would cost to make a you copy if you want. I couldn't find the second part number in the book but I did a search on http://www.partsvoice.com/ and found it. It seems the Doctor is correct. It is a pain to actually find the detail on all parts and there is not a single place to go for the information.
