[QUOTE="machoheadgames, post: 436479, member: 18789"] If it's the right spline then it will work fine. You'll need to change the front yoke to use your YJ front yoke instead. The 5-speed transmission can accept a long or short tcase input gear, so that's why the spline count is all that matters. You'll need 23 spline, if the TJ case came from a 4 cyl it's most likely 21 spline which is why that input gear needs to be changed if so. So figure out the spline count and go from there. [/QUOTE]
