i've had my 88 for a short while, i know the rear gears are from a junkyard, however i did not put them in, and i don't know what they are. On the differential cover it says 93. i thought it was just from another mustang. but today i notice that when i drove exactly one mile (i know exactly it is one mile) my odometer moved about 1.3 miles. What could this mean?

It means that your speedometer is off and you need a different speedo gear. What tranny do you have? You need to figure out what kind of gears you've got in there.

its an aod tranee. what is the easiest way to find out what gears i have. and how do i go about the new speedo gear?

Rotate the DS in a complete 360 and count how many times your tire has rotated.

i always felt like i had like 3:55 or 3:73's, cause i hear a lot of people talk crap about the stock gears, and i thought i was quick off the line. but then i thought it was just cause i use to drive my mom's minivan, this is my first car and im only 16

1/2.73(stock) x 1.3/x x= 3.549 or 3.55's

your information is incorrect. some cars came stock with diff gears, the only way to tell is look at the label on your door inside the jam. instance my car came stock with 3.08s some came with 3.23's & others came with 2.73's.

yep, i didnt think about that. I was under the impression that most of our cars came with 2.73 with a few exceptions. Am i worng?

im not sure how it was determined what gears, maybe build number, maybe special order?
