I have a dana 30 out of a 79 cj-7 and a rear dana 44 out of a 71 jeepster commando. I ran these on my cj for about 2 months. They have 4.56 gears and the rear has a lockright. Everthing is only 2 months old. I want to sell. I am converting to wider axles. It is already set up for a soa. The sua pads are still there. I live in Birmingham, AL. Please make me an offer. Thanks.
