Hey everyone. Weeks ago I changed the gears in my 1990 Mustang GT 5.0L w/ AOD. I went from the stock 2:73's to 3:73's. As you know, this has thrown the speedometer off about 30%. I have seen the correct speedometer gear in 21 and 23 teeth...which one do I need? I have seen the Mustang AOD's listed under both....I called two local ford dealerships, and its like im speaking a different language to them. One asked me of my tire size. Will that change what gear I need? (I have 17" Cobra's on it). Here is my examples on ebay. I'm including the link of the gear I believe I need...Please let me know if it is the correct one. Thanks!
