I had a 70 Barracuda gran coupe 8 3/4 housing mocked up in my 40 dodge. You only had to push the leafs out just a tad and the locating pins would pop right in to the spring perches. I wa told to use 55-57 chevy shock plates and it would bolt right up. The only thing is the chevy shock stud points out the front not the side like stock. later shawn
