There is no 9" that will fit your car. Any 9" you get, you will have to make it fit. If you have no welding or fab skills, open your wallet and give Currie Enterprizes the equivalent of your last 3 yrs tax refund and you will have a 9" that "bolts" right in. I have an '81 Cutlass with a 9". Your car and mine have the same G body chassis. I installed mine using ladder bars and coil/over shocks. I'm also trying to plant about 700 HP. You failed to say why you feel you need a 9". The difference between the car and truck rearends are that the truck rear is somewhat stronger due to it's heavier duty housing and 31 spline axles. But once you pass about 500 HP with slicks, you're going to have to scratch build a rearend any way, so what you start with is a moot point.
