Custom rear end for 67 barracuda

there is an other way . Set your spring pads at 90*. After car is on the ground and your ride height is set use tapered shims between the spring pad and the spring . Cost abut $20.00 . They are usually 2-3*. If you need to raise pinion up put shim in front . If you need to lower pinion put shim in back of spring . If you change tires or ride height you can change shims as needed .
