I recently acquired a '37 F-20 (shedded most of its life and in good condition) that was about to get hauled off to the scrap yard... now I'm gathering information about F-20s so I can start in on a restoration. (I know very little about Farmalls.) It has rubber tires front and rear, with round spoke front wheels and cutoffs on the rear. I'd like to replace the cutoffs. What rubber-tired rims were available for that year? I like the cast wheels... were those available on '37s? I'd like to stick with something that could have been original equipment on the tractor, but that's not an absolute requirement. Does anybody know where I might get my hands on such a set of wheels? I'm in central Iowa.
