Consider spending a few extra dollars on the SYE and get one with the larger 32 spline output shaft. Since you're doing an upgrade already, might as well get the stronger shaft.......down the road you could be happy that you did. We've seen busted t-case output shafts, especially in places like Moab, and it's not a pretty break. There is no trail fix for a busted output shaft, you have to go get another t-case. SYE's are offered with both the stock output shaft or the 32 spline output shaft.
Drivelines are standard fair double carden joint at the t-case end. They are all basically the same, so shop price, either a deal on a combination SYE and driveline or have one made at a local driveline shop. Usually it's cheaper if you get a kit that includes both the SYE and driveline.
