get a hold of Tim at Liquid Iron Industries. his shop is in west berlin, not far from you. he does installs for 300 with the axle still under the jeep, or 250 with the axle out of the jeep.
he rebuilt my dana 30 for me back in september
if anyone tells you to go to campers bobs, turn around. they charged me for timken master install kit, and a year later the axle blew. Tim kept the bearings to show me when i picked it up after he rebuilt it ..they were some cheap chinese white box brand. they wouldnt warrenty my parts or give me any type of refund for the parts i paid for but didnt get.
