My second post. Hope this ain't too soon..
Looking for rims for the back of my D. Parts book calls for AF1322R, but most references for that say 8" wide.
My certificate from Two Cylinder calls for 13.50 x 28 rear tires. The tire on the tractor (whats left of it) says 14 x 28.
Anyway, I measured the original rim and it is 11" wide drop center.
