Where to find bolt specs?

[Jakes-66-K10]

I recently acquired the factory assembly manual with the hope that it can guide me step by step through the re-assembly of my truck. But wow, this manual is impossibly hard to read. I can't make sense of the organization of pages, it seems they just made a book out of randomly placed truck diagrams - a lot of them having to do with the larger trucks which are of no use to me.... anyways my major concern is finding what sizes and dimensions of bolts to use in the various areas of reassembly. There are bolts shown, with numbers listed... but is there supposed to be a legend somewhere telling you that the bolt part number is "this" size of bolt?

I know LMC has great pictures and even some bolt kits but not all of them. I was hoping this manual would be the more comprehensive list. Any help would be appreciated.
