That's where we differ. I'd personally never degrade my Mopar with anything but parts for Mopars. I am a true Mopar or no car guy. Mine would sit before I'd put anything but Mopar parts on or in it. Yes very expensive but always have been. I got a Dana 60 with disk with a tru trac 4:56 from a guy in Colorado brand new delivered for 2500. Not too expensive. Mopar John. He's all over on eBay. Guy knows his ****. Just my opinion-
