my 90 sammy has been welded front & rear for 3 years--sportin 32" buckshots . never on road, in every imaginable circumstance off road---never broke any driveline part. it goes where jeep owners dont even like to look. as for the difficulty-- it goes together just like it came apart. its simple & im no diff man! when you weld the spiders you just dont build your weld too much, or you cant get the cover back on((((its very self explainatory))))
      on the down side--it takes an acre to turn unless you unlock one hub.anything other than a strait line is hard to navigate.
      personally---im going to put a locker in the front & leave the back welded & see what happens--i think that will work fine.
         thats my feelings on the matter--hope it helps!
IT WILL DEFINATELY TWIST THE T-CASE BRACKET THOUGH----YOU HAVE TO REINFORCE IT
