We added a rear crossmember to the lopped-off M38A1 frame. The beat-up old gas can is actually the fuel tank. It's held in place with a gas-can mount stolen from Hazel's M-715. The strap steel that keeps the can in the mount is some rusty shipping strap that we found in the fields while walking the dog. A scrap sheet of aluminum bent in a buddy's brake along with some angle iron and a few rivets cover the axlehousing that was poking into the bed.
