Rear End

It probably has a 7 1/4" rear in it. If there is a bolt on cover on the back of the housing that's what you have. Those are usable but not too strong. The 8 3/4" rear end has a smooth housing on the back and the carrier unit unbolts from the front. If you decide on one of those you need an A body one because of the width. You can find those for sale at swap meets, E-bay and on here from time to time. Because of their size and weight, hauling one home from a swap meet is your best bet unless you can find one close to home. Good luck, toolmanmike
