if you feel like changing the oil in the rear, it should say on the ring gear. but thats not a definate. if it doesnt, you can count the teeth on the ring and the teeth on the pinion and figure it out. but thats only if you feel like taking the cover off.

Are you talking ring and pinion, or the whole differential?
Remember, MN12's had IRS...a Mustang rear will not be a "bolt in' thing.

I *think* V6 (not including supercharged) MN12's had a 7.5 gear, all others had an 8.8 diff.
