Thanks, i can't quite make out the first # on the tag they are either 2.73:1 axle ratio w/ Traction-Lok or 3.73:1 axle ratio w/ Traction-Lok, i don't think i could have 3.73's because of how low the rpm's are at when cruising the highway. Does anyone have any #'s for me to give me a better idea? thanks!

If it's untouched I guarantee it has stock 2.73's in it, on my rear end when i got it I couldn't read the 2 either.

Ya, i'm positive its got 2.73's i just did a quick run and at 60mph, i'm at 3k in 3rd, around 2.2k in 4th, and just over 1.5k in 5th, i put those against the #'s i got off this calculator from allfordmustangs.com. and it has to be 2.73's. Is there any demand for the old 2.73 gears or should i just get rid of them when i get my new gears?
