IC2, thanks for the information, I will do as you recommended. I do have a large racing background, I know based on the center section that my rear end is an 8", I really don't have a problem with the 8" however, I would prefer to have the rear end centered and if I change it I will
go with a 9". My performance will come from a 390 FE with 500 HP 530 lb ft of torque. By the way Dave, you have a great eye I just checked my shocks and they are 40 degree's.
