Just wondering if anyone had pictures of factory bolts in a 1946 Chevy truck floor boards and firewall. Mine seem to be a mix of round slotted and flat slotted.
I don't have a picture, but have had several trucks of that era. The floor board fasteners are 1/4x1 flat head, and the toe board are 1/4x5/8 round head. All are slotted.
