Ok awesome thanks for that info. I posted an ad and found a guy a couple hours away who has a few trucks. He says he has a Dana 44 out of a '76 Military truck with the 4.57 gear I need. He also said he MAY even have a Dana 44 front and a matching Dana 60 rear out of a '72 GMC... both with a 4:10 gear! Awesome!! So as far as I know that would be a direct bolt on, front and rear, to my truck. Can someone confirm this for me please??
Either way it sounds like he is going to be able to help me out. He says he even might have the other brake parts I need to complete the job.
