Maybe some traction bars, but that's about it. I see you're running a powerglide transmission which has a very high first gear. This means you wont have as much torque trying to twist the axle out from under the car as someone running a turbo350 or a 700r4. This will make your suspension setup a little easier to do. I say, build the car and take it for a test run down the track. If you can't hook up the rear end, start spending money on it. If it does work with stock springs and minor modifications, you just saved yourself a lot of money.
