I know these questions might be better suited to a different forum (I figured I might get the most amount of traffic here), but I have noticed on a lot of pictures on there that there are some really nice look exhaust pipes and mufflers on some of the restored tractors. Also, there seems to be a lot of tractors that have brand new period accurate rear tires on them. I've looked and looked but I can't seem to find the tires anywhere. Any tips?
