Tech Tip from Ron Hansen
Alignment Solution for Installing a Late Model Rear End in a 1947-1954 Pick Up
On the original rear end, the spring centerbolt is offset to the front of the spring by 2″to 3″. If you install a modern rear end (with an open driveshaft) and retain the original springs, the wheels will end up offset forward (inside) of the original wheel openings in the fenders. To correct this problem, remove the original springs and reverse them end to end (front to back) as they are the same on both ends. This will bring the spring centerbolt to the rear of the axle and place the new rear end in the center of the fender wheel openings.
