1988 5.0 stock rear end ratio

to my knowledge - for 5-spd cars
2.73's - standard
3.08's - option

were 3.27's a factory option as well? dealer option?

From what I remember 3:27's were in the auto cars. Not sure of the year they started it tho.

Look inside the drivers door for a vehicle sticker. Look on the bottom line for a code labeled "AX". If the letter is E it is a 3.27. If the letter is a M it is a 2.73. If the letter is a Z it is a 3.08.

The E was only available with a Auto tranny starting in 1984.

Not all AOD cars came with 3.27s, some came with 3.08s....... I've owned several and its hit or miss it seems. Actually, the only Stang I've ever owned with stock 3.27s was my AOD equipped '92 World Series Parade Stang.
