what is the factory gear ratio for the rear on th 89 sc. if it helps, its a california car (that was where it was originally sold).
i did a run down on the vin #, but it doesnt tell you the rear gear ratio.
thanks in advance
 
Automatic transmission or 5-speed?

Try this... 'Axle Codes'. You'll need to cross-reference with the 'Axle' code on the data plate on your car.

3.27 While the Vin doesn't tell you.....the axle code on the "B" Sticker will if you can decode the letters and numbers. That info is in the front section of the Ford Shop Manual.
 
>i figured out the codes.

Good for you - always a good thing when you learn about your car.

Some people have owned cars where the transmissions have been changed (say from an automatic to a manual), and are surprised when the codes indicate different. Of course, axle gears can be changed as well, but the more information you have and the better you are equipped to understand it, the better your experience with the vehicle will be :)
