Hey ramman sorry took me a while to get back to you. But the tcase swap was cake, all that is really involved is tearing both case down and swapping the input from yours into the 231, that is if you have the v8 if you have the i6 it might swap directly in not sure. Just check the length that the input shaft sticks out the front of the case once you have both out in front of you. But I got mine from a 97 wrangler. You have to get a newer case cause the gear cut is different on the older model 231's. Thanks for the comments, she's my baby and is always gonna be a work in process. But thats part of the fun in all of it. Hope this helps let me know if you need anything else.
