Someone else will probably know better, but you might need a driveshaft since the Rubicon has a shorter yoke? (Possibly wrong)
I want to hear this story...
yea, sorta. If the OP has a 42RLE, he'll need the short input shaft (1-3/8" long from shaft face to mounting face). If he's got the manual, it's not an issue...long or short should work. all NV241OR's had short input shafts.
also worth noting you need a newer NP231J, 1996+. Shafts are different before that.
