i got my ford racing 3.73 gears yesterday from latemodel resto. cant wait for the weather to break to take the gt over to my mechanic and get um installed! its snowing here as i write this! they should wake the car up pretty good compared to the stock 3.31 in my car now! they came with a installation kit with new bearings and all the stuff needed to put them in and gear oil, and friction modifyer. now if only spring would come!!
