i know it can be done. i was looking into it myself. there was somebody on e-bay, that sold a kit for it. you need to redrill the mustache bar, you need to modify the driveshaft, make it longer, and also the rear brace. I am not sure about the halfshafts. but i'm sure you have to mess with those also. I would say it is a very big hassle for little to no gain over a good r-200. the r230 is also harder to find. the gain you make in the differential will be lost in the driveshaft, which will be weaker due to extra welds, and length increase. I think they are heavier also. Enough said out of me. If anybody has any other info........
