If ytou want to narrow it down evern further look for the casting date on the trans. There is one on the top cover on the pass side and another on the main case on the pass side. It looks like a circle with a number in it. That's the year the part was cast in.
Should be a yellow 7-tooth gear, look inside the hole for the speedo, you should see it
Speedometer Recalibration Gears
Once you change the gears in your differential, you need a new speedometer gear to recalibrate your speedometer. They're inexpensive, and only take a few minutes to change.
These Recalibration Gears fit 1979-1998 Mustangs. Please check our Hot New Product Section for information on 1999 and 2002 Mustangs.
Instructions: Note transmission type, model and resulting drive gear. Cross reference with your rear-end gear ratio to find the correct "recalibration" gear for your application.
