Stock rear gear was a 3.27,.. odds are the rear gear has been changed to a 3.73 or 4.10 and the speedo gear has not been corrected. And for point of interest. The T45 for 96 - 98 GT's has an 8 tooth internal gear. The largest external gear you can use is the 23 tooth Chrysler gear. Sadly,.. with the 7 tooth internal gear a 4.10 rear gear can not be corrected in the GT's. The 96 - 98 Cobra T45's have a 7 tooth internal gear. The 23 tooth gear works excellent with the 4.10 gear. And actually reports the 3.73 as a little slow. If you have a 3.73 it can be corrected with the 23 tooth gear. If you have a 4.10 you will need something like a Dallas Speedcal to correct it. That or swap the internal 8 tooth gear in the tranny and swap it for the 7 tooth from the Cobra.

As for the odometer and trip meter. This is typical of all 94 - 98 Mustangs. When your looking to buy one and the mileage is too good to be true,.. it usually is. The odometer in my 96 GT quit at 63k,.. but I can assure you that 6 years later the original mileage was not 63k. It was closer to 230k. Ask the previous owner how long ago the odometer quit working. If it was already broken when they got it,.. well,.. there is no telling how many miles are on that car. Ford dealers sell a repair kit. Very easy fix.
