Hi, first post on the forum. I have a 2012 RWD Charger with V6 and 8 speed. I have access to the 3.06 geared rear end from a salvaged AWD charger(same year). What I cannot seem to determine is if it will bolt in place of the existing differential or if I will encounter additional modification issues. Mopar customer service has not returned several emails. Before I drop the money on the differential I would like to know what I am getting myself into. Any ideas or thoughts?
