So I am fixing issues caused by the previous owner. One of the things they did was swap in a donor trans with a 231 case in place of the 242 after they blew it up. After some of the dumb things I've found on this jeep that they did I'm curious if they used the original driveshaft. Any of you have the measurements for the driveshaft for the two options of this year? Also what reference points are you supposed to use when measuring? I've put a 2" lift with rear blocks on it (swapping the blocks for a long add a leaf tomorrow) and after checking my driveshaft, trying to pin point a clunk I have after taking off from a stop, I'm worried it may be a bit short for proper spline engagement.
