I just changed my diff yesterday. Finally broke the R180 on the trip to and from MSA. A while back, when I also got tired of the driveshaft/handbrake interferance, I changed over to a Ron Tyler mount. It made changing the diff simple, one bolt. Rons design also has the advantage, for us V8 guys, of being able to lower the nose enough to get proper u-joint angles. I did have to cut a section out of the crossmember to make clearance for the larger R200 snout. But this is no big deal as all it does now is just clamp the LCA bushing to the body.
