Question - Factory Assembly Manuals
 

i'd say less than 1% of the illustrations in the assembly manual actually tell you what size bolt it is. but you could buy an assembly manaul and as you're assembling write down the proper sizes so you can tell others in the future!!!

Assembly manual will not have the bolt sizes but will give torque requirements for most of the bolts along with drawings of the assembly process. Bad part is there is not a lot of order to parts of it and no table of contents to help find things.
Service manual will tell you how to do the repairs, but no bolt sizes.
If any of the bags/boxes of bolts have part numbers, you may check with Joe to see where he bought most of the bolts. Then just check their web site or get a catalog and look up the numbers.

The "Assembly Manual" is an interesting book, but it's not what it's advertized to be. It is really a collection of dealers' RPO drawings for many of the various mods and options these trucks were sold with. That's why there's no index, no explanatory text and no part #s or hardware sizes. If you look closely you'll see a gap (about 1-1/2" or 2" long) where the original 7-digit GM p/n was whited out. These numbers like 3815891 tell the service technicians what the part is and what bin to get it from. If you went into a Chevy dealer's tomorrow with the right number, there's maybe an 80% chance he'd have that part or numbers to a part that supercedes it. Why delete it? Good question. Maybe so outfits like LMC, who sell a butt load of these so-called "Factory Assembly Manuals," can get you to use their part numbers so you'll buy from them and not the dealer? Or maybe General Motors doesn't want their part numbers published in a book they have no control over. I'm only guessing. Copyright infringements, perhaps?
:bowtie:

Yeah, I found I couldn't make heads or tails out of it. Maybe that's just me though. I always had trouble following along with Snowwhite and the seven dwarfs too. :D

That deal about the part numbers must be new. My manual is pretty old and the numbers havn't been censored out in it.
