Here is a shot of my rear bumper carrier on my tan '40. In this shot it is configuered as a dual can carrier. The driver side swing arm can be removed and replaced with a tire carrier instead of gas can rack. The can racks also work well for coolers, Ammo can, duffle bags, or whatever (the shot on the latest cover of the TT shows the rig with cans on one side and a cooler, ammocans, snatch strap, chairs and stuff like that in the passenger side rack.
I've done this on a handful of rigs ('40s and '60/62s), but this is the only shot I have handy.
Most of the folks keep the tire carrier in place, but since I carry repair gear for the tires instead of carrying a 39.5x18 inch bogger on the back of the rig,and the distance of the trails I play on calls for lots of fuel... this is how the back f the rig usually looks.
