Truth is, I know so little about axles. My buddy had a built XJ that he blew the motor in, so he used some parts from one, and some parts from another, and built his current rig, the d44 was left over, so I picked it up from em.
Glad to see you came to your senses.........and don't get your panties in bunch, we're having fun here as well as trying to exchange useful information.
I can tell you what I've done, but if you do a search using "leaves" and posts by "Goatman", on "mod tech" forum showing "posts" (not threads), you'll get quite a bit of info, and it's much easier than re-typing it here.
I agree with Goat (like that's new), leafs in the rear is the only way to go and he's gone a long way to make them work well. Getting 8-10" isn't that hard, National makes a nice 10 leaf pack that will get you 6", a long travel shackle for the springs will be about 1" lift and then you add 1" raised perches (or 2" like mine) and you've got your 8". Make the perches long & wide and you'll fight axle wrap. You'll have a spring pack that works well and gives you trail feel without the 'unloading' affect of coils or coilovers.
I dont currently have any axle wrap even with 38.5s and 2" lift perches. I probably will when I go to an Atlas which is why I've been considering a 4 link rear but I haven't seen rear coils that offer the control & stability of leafs. Maybe with a good swaybar & lots of trial & error it could work well.
