We would need to know what rear tire size you have to more accurately choose what gear you would need. For your 91 with an auto transmission it would have come from the factory with a 8 tooth drive gear. You can enter your information here https://lmr.com/products/Mustang-Speedometer-Gear-Calculator and it will tell you what gear you will need.
