Feeling lazy...What rear gear do I have

[WhiteGT]

I know I can jack the back end up and rotate the tires just don't feel like getting stuff out to do it so my question is what rear gear do I have. It's a 95 gt 5spd in first gear at 25mph I'm at 3500rpm.
Thanks for the help

Why don't you get under the car and figure it out. You're welcome.

The tag will have a 3LXX the XX is the ratio.

I don't think it has stock gears. If it is it's 3.23

Do you mean 3:73? A stock option with the AODE is 3:27 though.

How do you know the spedometer is correct?

I've never seen 3:23 gears, can't be what the tag says. Ford never put 3:23 in 8.8 Mustang rears. Should be the 2nd line, closest to bolt hole.

You can also jack the rear, turn the tire 1 complete revolution, and count how many times the pinion turns.
