87Warrior Posted November 1, 2015 Share Posted November 1, 2015 I want to upgrade to a 231 tcase in my 86 MJ that has a 207. I currently have a good 231 tcase from a 91 with the electric speedometer sending unit that I would like to convert to a cable driven sender. I need the gear driven parts that bolt on the t-case tail cone and the tail cone from an early 231. Willing to buy a whole parts 231 if you are relatively close to Kansas. Thanks!

mvusse Posted November 1, 2015 Share Posted November 1, 2015 Get a cable drive unit from any older 231. You don't have to swap out tail shaft or tail housing, it will be a direct swap involving 1 single bolt. Even one out of a 2wd AW4 should work, exactly the same. I wouldn't be surprised if your old one from your 207 would fit as well. Link to comment Share on other sites More sharing options...
87Warrior Posted November 2, 2015 Author Share Posted November 2, 2015 I did not realize the tail housings were the same for the cable/electronic 231, thanks for the tip. I will check to see if the 207 cable unit will mesh with 231. I was under the impression the two were not the same length based on some limited research. But hey, I will try the easy way first!
