transfer case ?

Will this transfer case work in my 90 jeep wrangler 4x4 with straight 6, 5 speed? This guy said it would but im not to sure. Im kinda new to this jeep stuff. I found this off craigslist. i was told it has to be a 23 spline but who knows. And also what driveshaft for the rear? Thanks

88 Jeep Comanche 4.0 renix, 5 speed BA10 trans(needs bearings), NP231 transfer case with fairly low miles. I dont know the engine mileage, but no knocks or ticks these 4.0's will run forever. The entire engine package runs great and it very reliable, I drive nearly 100 miles a day without missing a beat. It's been cleaned and painted recently, new gaskets, newer injectors, tuned up, K&N air filter, new alternator I havent even installed yet, new crank sensor, polished valve cover. All accessories, intake exhaust, engine wiring harness, mounts, basically everything. This would be a perfect 4cyl swap or mud buggy engine, its a complete running system. $500

As said before, the 5 speed BA10 transmission is bad, but the np231 case mounted to it works perfectly.
I also have a spare t-case, both are 21 spline NP231 units in good shape. $150 each
Also for sale I have an 87 Cherokee automatic trans in good shape, and most parts needed to use the auto on the stick engine(missing the wiring between the TCU and transmission harness) $100
A well worn, but seasoned, auto engine that could be rebuilt $100
everything all delivered within 50 miles of downtown sarasota for $1000, further for a bit more.

It will not work unless you change the input on the tcase which means you have to disassemble both tcases.Your trans is 23 spline and the BA10 is 21 spline
