I believe that is 2.73 ( axle code " M " )
I had a 1991 Ford Mustang 5.0 L - LX - automatic , and it had 2.73 's
The rear end ratio for a 1991 Mustang GT typically comes with a 3.08:1 standard ratio for automatic transmissions and a 3.55:1 ratio for manual transmissions. However, some models may have different options depending on specific configurations or aftermarket modifications. It's always best to check the vehicle's specifications or the rear axle tag for exact details.

5 QUARTS 5W/30 FOR A STOCK CAR
My 1991 5.0 L - LX with 4 speed automatic and 2.73 gears could get 25 MPG ( U.S. ) on the highway ( if it wouldn't get 25 , I figured I must be bucking a wind )
I don't know if it is the same but my 1991 Ford Mustang 5.0 LX had 2.73 gears with the 4 speed automatic transmission ( at 137 MPH it was loafing along at 3300 RPM in overdrive ) * I believe the Traction Lok axle codes in a Ford Mustang up to 1993 are " M " / 2.73 " Z " / 3.08 " E " / 3.27 " K " / 3.55 " W " / 3.73
My 1991 Ford Mustang 5.0 liter V8 ( LX ) had a compression ratio of ( 9.0 to 1 from the factory ) ( 8th " character of VIN was an " E " )
It's suppose to have a stock top speed of 140, but I never got mine past 134
USAAF Mustang happened in 1991.
