Look for a front d44 from an '80s model Wagoneer, same width as your stock axle but has a 6-lug wheel pattern.
A great rear axle to compliment the Waggy front is a rear d44 from an Isuzu Rodeo or Honda Pilot. They've got disc brakes, similar width to the Waggy, same 6-lug wheel pattern, and disc brakes. It's what I run.
Easy way to get front and rear d44's, and 4whl disc.
