i have a 72 cuda 4 speed car that I am looking to upgrade the rear suspension on. The car currently has orginal springs on it that I am sure are sagging, but the stance is perfect. Howerver upon acceleration the car will squat in the rear from the wore out springs. So,I was looking at installing some super stock spring but was wondering if anyone knows or has a rough guess of the ride height that would result from installing the SS spring. Or if the ride height could be adjusted by getting the springs that are listed for a lighter car. Thanks for any insight
