I have been in the search for a 4.56 or higher rear gear. I was reacenly offered by Bill a rear from his K20 parts truck. He is sure the front was a Dana and the rear is a 4.56 Posi Detroit. My question is 2 things, is or will it fit a HO72 and secondly will it fit my DRW axle.

Thanks Everyone for your help to this new young bolter!
