i have a narrowed 9.25 to A body width with 8.75 axle ends to eliminate the C clip---you have to buy a custom axles for it-----drag race guys have to use a C clip elimination kit and the ford 9 inch axle end is the most common one to use--(-you can use 8.75 axle ends also like i did)----my axle runs a 2.7 posi that i first envisioned as a bonneville axle for my 64---it now is under my 50 hudson as a cruiser set up......
