Mopars typically don't wheel hop unless something is amiss. Chevy's are notoriously brutal wheel hoppers unless you run ladder bars or something.

A snubber should be touching the floor on a stick car, which is just too brutal on the ride quality to live with even for a short time.

(Although determining pinion angle is a confusing and contested subject)Check your pinion centerline angle in relation to the engine/transmission centerline angle. Let us know what it is. You can use a cheap magnetic angle finder available at most hardware stores. Remeber you are measuring the angle on the front of the rear end and on the rear of the engine/ trans, so be careful how you compare the angles in relation to each other to determin the pinions angle in relation to the angle of the engine trans/ centerline.

I bet it's off. You can use spring perch wedges to get it corrected up to a point. Then comes relocating your spring perches.

Correcting the pinion angle and clamping the front spring segments, and possibly removing some clamps from the rear segments should be all you need if you have some decent rear shocks.
