Ford 3:73 Motorsport Gears July 30, 2006, 07:58:55 PM I have an 88 Thunderbird Sport with the 7.5 inch rear end. I am going to be getting some rear end work done, so i was thinking of changing the gears while its all taken apart. Does anybody know if the Ford Motorsport 3:73 gear kit for the 7.5 inch mustang rear end will work in the 7.5 inch rear end in the Thunderbird?The Ford Motorsport parts number was M-4209-L373 MThanks Quote Selected

They fit and work fine. Quote Selected
