Normally go to bed at 10 and wake up at 4.
Need a 23 spline 231 with a medium or short input depending on your trans, assuming you don't have a rare ax15 ZJ. Not sure how linkage works in a ZJ but should just bolt right up and be ready to go... If you find a medium (1.7") input shaft it can be trimmed down to 1.2", chamfered, and deburred, and be ran that way too. Done 2 that way and know a few other people who have also done it.
