NO that wont work!
I asked the question of HO 52 or HO 72 rear because of Lug patterns and tonnage.
HO 52 is 1/2 ton 6 lug bolt pattern since Christ was a Corporale till about 1972.
HO 72 is the style rear you need in a certain year,because you can pull your axle shafts and pop out the old ham, and then just Slide the axles back in.
