Hello everyone looking for info. I just bought a new set of 28" x 10" rims for my 1946 2N tractor ( second set i tried ) and my center section doesn't fit. Are the newer versions made with heaver gauge steel. Has anyone had this same problem, do you grind the center hub or do you grind the rim tabs to make it fit. This is my second set i tried first set i sent back because they were made for bolts and i want carriage bolts for mine. So i ordered a second set and they are the same. Any info will help.
