Hi I have a 91 mustang 5.0 with the AOD transmission in it thats having issues. I am really interested in t5 swapping it and I have found most the information on how to do it and what I need. But I was wondering if I would have to change the rear end gears and what I should change them to. I have a 8.8 rear end in my car with 2.73:1 gears and I'm just not sure if or what to change them to. Does anyone have any recommendations?
