For anyone following this post, I just got the Jeep 10 spline shaft and all the seals and bearings. I expect to be pulling it apart for the swap pretty soon. I had my clutch inspected before doing this and it was deemed to be in really good shape, so I don't have to change it. Lugnutz has a really good blog that covers the Jeep shaft swap, and I am reading it several times to make sure I am ready to do it. Wish me luck!
