I think the major difference between modern automotive wheels and those used on older farm equipment is in the diameter of the center hole which fits over the hub. Wheels from some older pickup trucks might be worth a try. Take one of your hubs to an older salvage yard and try the fits. On the Dearborn the front wheel's dish depth must be about right or turning radius will be affected.
