I have a 9" Currie in a 69 A-Body. I can't say for sure how they will work because the car is not built yet, but I elected to go with the Currietrac upper arms and lower trailing arms. They have Johnny Joints that can be greased. I also installed the Hotchkis frame braces. I am assuming the wheel hop you have would be from drag racing? If so you may consider air bags to pre-load the coil spring. The pre-load worked for me on a 66 B-Body that was a drag car. I am not sure about angle but I think asking Currie would be good. Here is a link on the arms

Good luck.
