Hi, first post! I searched The forums and couldn't find an answer. I have a 2006 Dakota Quad cab 2 Wheel Dr. with the Chrysler 8 1/4 rear axle. I want to put in 456 gears because I am running 33's on it now and I have the v6. I'm curious if the Chrysler 8 1/4 from a Cherokee XJ is a direct swap as I saw an ad locally for someone selling one with those gears and a locker already installed.
