Hey ya'll.
Im looking into doubling up a t-case setup on my xj'. Does anyone lnow were I can find Transfer-case doubler kits/adapters for a jeep np231/np241? Is there any companys/shops out there that sell a kit/adapter?

I did a quick search on google, but only found doubler kits for 205's and 203's.
I would consider swapping in a total different t-case setup doubled, but Id really like to find an adapter/kit for the jeep np231-np241, since I have a 241 in my current xj, and I have a 231 in a parts jeep.
I just want to build a rig with unlimeted capabilitys, and Ive been wanting to twin-case a jeep since I could remeber. If not, what other options could I go with besides just re-gearing the diff's(already have 4.56) and getting and atlas.
Thanks.

Never seen a 231/241 doubler. Maybe some of the old school divorced cases might be made to work, something like a DanaSpicer 24.

even if i can find and adapter to adapt a 231 to 231, 231 or 241 to d300, and since the np205 is actually the same as a 241, maybe and adapter for a 231 or 241 to 205.
Any other ideas?
Ive come to the conclusion, I will spend some cash and buy a diff' setup of t-case's, But what would be a good fairly cheap and fairly easy set of t-cases i could double up and make fit in and xj?
Anybody know anything about dana300s and were i can get a flip kit? and what all do you have to do to swap a dana 300 into a 89 xj auto? Cuz I can get a dana300 for 250$, but wanted some info on what I'd have to do to swap it in, and some personal opinions of you guys out there that may have done it.
thanks.

how about a 231 to 231 adapter? Or 231-205? or something to adapt a 205 to.
Thanks for your input, but i wanna keep with the NP cases, possible a dana300. I dont know much about dana cases, Ive rebuilt NP cases more time then i can count so im familar with them, and wanted to stick with them.
