It's about 2" longer. My rear driveshaft had plenty of room (sye'd)
Best wiring I found was here
...I used a 91-96 Cherokee trans. The only real thing that had to be fab'd up was the trans mount. I used the ax15 mount, bolted to a 1/4" plate. The tc shifter needed a bracket made up also.
There's tons of info around. Pretty simple to do for the most part. Didn't run into any real problems.
