New clutch installed and bad wheel hop?

Thanks Rmoore I hope the issue is that simple. How do you change/adjust pinion angle and how do I properly measure it?

Go to the hardware store or tractor supply and buy an angle finder ! Look up on YouTube on how to check pinion angle ! To correct you buy angle shims from anywhere Summit Racing, Mancini Racing, etc !!! Rusty on post 6 is right also! Leaf springs being worn out can cause the pinion angle to be off !
