I'm in the middle of a swap. I'm just using my same rear end that has 3.73 gears in it. I decided to pull it all part and replace bearings, seals, gaskets, rear dif cover, and intall a new eaton trutrac carrier. Just about finished with it. From what I've read, it's not so much the rear end that needs swapped but possibly the gear ratio depending on what transmission you decide to use with your swap? Also, (and I'm not this far along yet) you need to decide how to get the power from the trans to the rear end. There are some decisions to make in deciding whether to get a custom driveshaft, center carrier issues, and maybe might be able to get by with some yoke modifications to original stuff. I'll know more on this later.
