For starters, I have a 2014 V6 mustang with the automatic transmission. I've been modding it recently and have decided to go through with changing the gears on it. I want to upgrade the gears to the 3.73s but ran into a compatibility issue. I found someone selling their rear end (8.8 inch w/ the 3.73s) for a 2000 gt, but wasn't sure if I could just take it and install the diff onto my car. All the diffs on American muscle have the 8.8 inch diffs compatible from 86-14 for the V8s, and 11-14...
