I try to take photos pre-disassembly, but it's hard to get them all. If you have specific locations, some members with similar trucks to yours may be able to help out. I think it may depend on the assembly plant as well. Canadian assembly plants were/are fond of using Robertson (square recess) screws. I once had a Model A body that had those almost exclusively in the smaller screw sizes.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
