TrackerJoe, welcome to the site man!! I've read here somewhere that a locked 2wd is as capable as a unlocked 4wd. I say go for it! As far as the 4x4 conversion, I think the front axle and hard ware will work, but I'm not 100% sure. You will need the T-case, axle, cv shafts, front driveshaft, and knuckle/bearing/locking hub assembly. There may be some other stuff like different crossmember for T-case, and different rear driveshaft. It sounds complicated but it's definitely worth it.
