Re: Rear gear ratio?
Some....91 GT 5-speeds had 3.08 gears
............91 GT AODs had 3.27 gears
From what I have researched, they came from the factory with 2.73 gears, but owners could check the gear ratio change box and get the ratios listed above installed for free.
Just look at the tag on the rearend. It will tell you what you have, or had if someone changed them.
Or, you can remove the cover and count the teeth on the ring and pinion gears, then divide the ring gear tooth count by the pinion tooth count.
