I have the stock axles out of my 79' CJ-5 for sale. I put one tons under it and no longer need these. They have under 1 mile on all new bearings, seals, and brakes. They are 3:54. The rear has a lock-rite and the front is open. The Dana 30 has Superwinch hubs. These are 5 on 5.5.
$300 for the Dana 30
$400 for the AMC 20
