        Fits great!

        Very cheap add-on to give you the correct readout on the speedo for your gearing and tire size. make sure you find a calculator to determine the tooth count using gearing and tire size. If not, you can be way off.

        Correct part, but not for my set up

        After purchase my stang, I notice the car will run to hi in RPM, well it had a 3.90 gears, I changed to 3.73 and try to correct the speedometer with a new gear. I call AM and a service rep was really helpful and after some digging he told me that I was in need of a 18 tooth gear! well got it. Well for my luck the gear work fine but the speedometer is still out of whack, my tranny gear is an 8 tooth not 6 as I and the service rep though. Overall is a great product and is a Ford OEM part.

      What speedo gear set is needed for a T5 with 3:73 gears and a 140mph speedo in a 1988 LX efi with mass air conversion.

      • For a 1988 Mustang with a T5 and 3.73 gears, you would need a 21 tooth speedometer. You can find that here: https://www.americanmuscle.com/speedo-gear-21tooth-manual.html
