Bolt And Nut Reference Guide

I'm not sure if this is the right place to ask this, my 1971 Demon 340 has been in a body shop getting restored for the past seven years. The gentleman working on it passed away last month. He has parts scattered everywhere in his shop. Once I get the car painted, I will have to be the one to put it back together and will be needing a nut and bolt reference. Is there anyone out there who sells such a reference book? I see MMC Detroit has a general book but nothing A body specific like they offer for B and E bodies. Thank you everyone.
