I will check through my documents and make sure I have posted everything that I have. As for manufacturing one, i have not found anybody that has done so. You can use a later model truck under bed carrier with some creativity. I have an extra slider but those are relatively easy to find. The hard part to find is the actual carrier that holds the tire to the bottom of the bed.
If you are looking for a carrier that attaches to the side of the bed (not original but looks cool), there was a guy a few years ago manufacturing a really nice one but he stopped a few years back. Maybe if you check with Chevy's of the 40's or Carter they may be able to point you in the right direction. I'll dig through my paperwork this afternoon while watching the Packer win another game.
