Ok I`ve finally decided to stop screwing around and get an Atlas for my MJ. My ? to those that have installed an Atlas in a XJ or MJ with and AX15 is whitch shifters did you use and is there anything additional I will need for the install? I plan to pull the 231 Fri and verify the spline count and determin if the spacer will be reqired. I am on a restricted time frame so I don`t want to get into the install and have to wait on anythig besides the drive shafts. Thanks.
And I did search first but got nothing specific to my questions.

on my defunct XJ i used the TJ shifters.
I sold her to Sean P and apparently he heated up the shifter rods and bent them a little bit and greatly improved them.

also, seems like you already know about the spacer, so thats it really...good luck!
