Does anybody know where you can find the "part discriptions" or part name for everything listed in the "1947-1954 Factory Assembly Manual"

In particular, the bolt discriptions. it gives the "bolt number" for every bolt on the truck, but I wanna know what those numbers mean, like "###### = 1/2' X 3' coarse thread hex bolt"

You would think there would be a parts list in the back or something but I cant find anything in the book or online

thanks a bunch
