72 A body door fasteners

Hi all,

I have a partially disassembled 72' Demon, I would like to put the doors on it before I do any quarter panel/rocker removal to check alignment. The problem is that I am missing the fasteners for the doors. Anyone know what size and grade bolt would work as a replacement?? I'm guessing hot dipped galvanized would be the way to go as far as coating. your thoughts?

Thanks,

Joe
