Rear end higher than trans output...okay?

[dontlifttoshift]

You need more clearance from the driveshaft to the tunnel. You need to get those working angles lower, because right now they are probably about 5* You can:

A. Raise the tunnel, as Don stated. It's a solid plan and would solve your problem.

B. Roll the pinion down, a lot, until your working angles are the same.



Both of those options work. Both of those options can be a lot of work. If the 4 link was set up for the pinion to be way up like that, you may end up with problems rolling it down, such as bars being too long or short and the bearings in the shocks binding through travel.
