I just got my 96 GT a couple weeks ago. one of the 1st things i noticed when i was test driving it was that the speedo was way off. dealer didnt know much about cars but was told that the rear gears had been changed, which was pretty obvious during my test drive. car is much quicker then the other mid-late 90's stangs i drove. the car has been fantastic (cept for the annoying 2-3 grind when shifting). the main problem is that the odometer registers about 1.25 miles for every mile i actually drive. i dont know what was the standard gear for the 5-speed gt or what the gear was changed to. what i want to know is if it just needs a computer adjustmennt or a mechanical change on the speedo cable.
