Well, me being eighteen and all, I have no clue what I'm doing.

Anyway, I was wondering on a long bed of a 1938 Chevy 3/4 ton long bed, how many rails are going across that are under the wood and wood rails?
I currently have two of the originals located evenly apart from the front two the back, the spaces are even, but I don't know if I'm missing some seeing some restored beds with a bunch of bolts through the wood rails that run long ways with the bed.
I'll try to get a picture if needed, but before I go painting the bed, I want to make sure I have everything on the bed that would need to be painted. Thanks.
