Rearend Build Butt Weld

This early housing was used from the birth of the 9-inch in '57 and carried through till '77 on some applications. It has always been a favorite for hot rodders due to its nice round pumpkin...come on, guys! But it's weaker than the later housings because it used a butt weld to join the axle tubes to the center. In a light hot rod, much of the early stock stuff is OK because the car would smoke the tires long before it'd break the rearend, but not so for full-size cars and trucks. View Related Article
