Wheel hop in REVERSE?

Well i added the 2 degrees more this morning so now i have a down rear of 5.1. . I don't see much if any diff from last time. If i slip clutch i can make it work. Don't know what else to do. All bushings seem good, motor mounts seem good. If any of yall live in york pa and want to take a swing at this thing, literally a 10 pound sleg swing i can make it happen.

Might end up being a clutch issue. I've never seen a clutch chatter "only" in reverse, but there's a first time for everything. Have you checked the transmission mount?
