run a waggy front and run a adapter in the rearOr be cheaper all around, sell the XJ D44, buy a pair of waggy axles (mine where 100 for the pair) and go from there. gears, brackets, shafts, brakes ect to build them will cost the same. Or run the 30 till it breaks and shows its self as a problem. then worry about it...

Its mud flap time! Got pulled over for a "tail light and license plate light" violation, had my car searched, found I didn't have mud flaps, lights work just fine... I guess I'll get off my butt and finally make them...

If you do an Atlas...yes 
If you want to try a 4:1 in the transfercase, you should be able to accomplish it for much less than that. A kit would be $800 - $1200 new. But if you can find either a NP231 or a D300 that has one in it already, it would be cheaper. Most (or all as far as I know) D300's need to be run upside down, since they came in rigs with passenger side pumpkins. The NP231's are more straight forward.
While the planetaries CAN burn up in them if you go too fast, they are no death trap. You just need to be good about switching to high range when you get out in the open and want some speed. If you stay out of 4th and especially 5th gear in low range with a NP231 4:1, you should be fine. When we are both on the trail some time, you can ride in my rig and I can show you the difference between 2.72:1 and 4:1. It is totally worth it when you have a manual trans IMO.
