OK, I've found sources for resin Rockwell 2 1/2-ton and 5-ton axles, plus 66-inch flotation tires (or Terra Tires, or whatever you call them), but I've yet to find anybody that makes the 48-inch flotation tires...you know, the ones found on the really early monster trucks. Does anybody know if I can find any, and if so, where? I've got a couple ideas for old-school monster trucks.
