I recently ordered a 1947 -1954 Truck assembly Manual I believe from Brothers, it is over an inch thick and has been a valuable asset. I think it was brothers but, if you can't find it, I will try to find out which vendor. Also old trucks that are restored don't rattle. A 12x12 sheet of full grain cow hide and LMC frame gasket kits will solve all squeaks, rattles and bangs.
