rear end swap help?

It can and has been done with the Jeep 8.8 and Ford Ranger both.
Both have the 4.5 x 5 bolt pattern too.
The long of the 4x4 axle needs to be cut down to the same length as the short side, and then another short side axle is used on the newly shortened side.
The perches for the springs need to be moved also.
The driveline needs to be shortened and a different yoke used at the rear.
Also, apparently the E brake connects right up to the Dart cables.

I looked into it quite a bit for the diff lock and disc brakes for the rear.
It's out there if you search it on the net.
