The numbers on my data plate I pulled from my axle are: S2921A B
373 A75 9F26
I know this is a 7.5 rear, I think the gear ratio is 373. What letter or number in this code designates this as a limited slip or convential rear? Also this is in my Stang Im still swapping the 5.0 into. Im not going to run it to hard. Ive heard that the 7.5s got a bad rep unjustly and they will hold up pretty good. Is this suitable for my almost daily driver,maybe a wheel spin now and again. Thanks

 

is this the info from the drivers door? look at the chart and get the letters from where it says AX yes the rear end is a 7.5 but i cant figure out which gear you have by cross referencing with my book
