I have heard that you have to trim the trans tunnel a little bit but if that's all and my stock console will still work then I will be good to go. So if anyone has done this swap let me know im not sure how long mine is gonna last and I'm not sure if my buddy is going to hold on to that trans much longer.
They are a 100% direct swap between the two with no mods needed. No trimming required. The same clutch slave works, same wiring harness, same t-case, same shifter boot, and you won't even have to remove the clutch and pressure plate if you aren't swapping to new ones.
