Rear end swap into Rx2

And i have been reading up on 4 link set-ups do put the 8.8 in. The only part that I'm really confused about is how to mock up the rear. As in the height. I know I'm supposed (or at least i have read) to set the links/suspension as if the suspension has full load on it. So how do i know how high or low i should mock up the rear end?

Does that depend on my shocks, link set-up, or any other aspects?

The biggest thing is to maintain the pinion angle. When I had my 8.8 built for my 7, the builders laid both the -SE diff and 8.8 on wooden horses. They measured the bracket and perch locations on the tube in relation to the face of the pinion and cut and welded accordingly. You can build adjustable 4-links using threaded tubestock and heim ends if the pinion angle is incorrect, allowing some adjustment.

Are you planning on using a panhard rod, or watts link for stabilization?
