You should be able to make a Chevy spare tire mount work. The holes may already be there. The '50 or '51 and later use a single support that runs diagonally across the frame on some long bolts. There are also a couple of u-channel pieces across the frame rails.
Other guys have mounted modern truck spare winches under the bed.
