Normal stuff like front and rear main seals would be worth checking. Also, the side cover (on the distributor side) can sometimes leak, snug up the bolts and see if that helps. Otherwise, t-case output shaft seals...
Good luck on the build and welcome to the forum! With the SOA you might want to have a traction/anti wrap bar and make sure your steering is okay (caster angle). Otherwise, have fun!
