The Ford Barn - View Single Post - Will a 46 rear end fit into a 41 without modification??

The 1941 is the last of the narrow rear axles. The wider axle came along for 1942 and continued through 1948. The later ones use a panhard bar too. The wider axle will bolt up but wheel spacing in the fender well might be problematic without changing the wheels for more backspacing. There is near an inch difference on both ends for a total of near 1 3/4 inches over all. Axle shafts are out there. You just need to use the correct tooth count when interchanging them from 1937 thru 1941. There were two different tooth counts between the end gear and the spider gears.
