People have a mis conception of how they hook so well. You think you can add a set of Leafs and a pinion snubber and hook like them?? Good luck with that. There is alot that goes into a car that hooks with leafs also. If you think it is a bolt on deal, you are in for a surprise. Especially with 1000HP/Torque to the tires!:D
Plus I can't stand the 4x4 Look on an A Body with the *** end sticking up in the air, it looks like chitttt to me. The Wheel Lip must be burried in the wheel well. Try that with some Leaf Springs and then try to get it to hook....... Yeah right.
