we've been using junkyard rubicon rocktrac t\cases they already come with a 4:1 and beefed up parts we just have tom woods order us up some 1310 style yokes and seals for it and i think they do a little machining to them i can't remember and boom oh yeah they are also already the 23 spline short input aswell.
Thanks! Good to know! Frankly, I was figuring the t-case would be the least of my worries. <img src="/forums/images/graemlins/smile.gif" alt="" /> I hadn't even thought of using the RockTrac. I was planning on doing the same ultra-short shaft conversion on a NP231 w/ the Terra Low that I did with my big Sport and dropping the Dakota SGI in for the speedo. But, the RockTrac would almost certainly be cheaper. Choice will mostly be based on overall length of assembly (edge of bell housing to output yoke on the t-case) and whether I can get an electronic VSS.
I've been through Dakota's stuff. Great products! The GPS speedo looked great and I know others that are using it, but the SGI is simpler and 100% fool proof. Just need an electronic VSS.

Does anyone have the length of the entire assembly? Edge of the bell housing -> doubler -> t-case output yoke? Pictures look like the A/T setup is longer than my M/T setup but its really hard to tell from just a picture. If its shorter than what I have now, I may well want the extra length to clear the rear cross member and maintain my existing drive train geometry.
Ok. Let me make sure I understand this. The Montero V4AW3 - that I need to bolt to my '99 3.5L - needs the 23-spline output and tail-housing from a Cherokee with the AW4/NP231.
The t-case needs the short snout 23-spline input. Is there a reason its the short snout 23? Wondering, because i have the long snout in my big Sport now and I was under the impression that the AW4 came in either short or long.
