    Ok, having trouble figuring out which speedo gear I need. I own a 1991 Mustang LX 5.0. Manual Transmission Coupe. Running 225/55/R16 Tires Checked the Rear axle tag and if I’m reading it correctly I have 3.08 gear ratio 8.8 diameter.. I have to assume the o/e gears have not been changed as I bought the car with 50,000 original miles. It Had sat in a garage for 12 years undriven.

    • The 20 tooth speedometer gear will work for a 1991 mustang LX with a OEM T-5 transmission and 3.08 gears. If you have another transmission than that would require another speedometer gear.

      Quality

      I love American muscke and have ordered quite a bit from there. I called in and told that I have 4:10 gears, and was set up with this. It works well and correct the speedo! Super easy and straight forward to install as well!

      Great price, right part first time...

      Brought my speedometer right into perfect calibration! Prior owner had replaced the OEM 3.27s with 3.55's. For me, recording the correct mileage is key for a limited edition car. The tech support team got it right the first time!!!

      Spot on

      This in combination with the other piece I needed from American muscle worked perfectly to properly adjust my speedometer to the correct speed. I tested it on a speed trap thing set up on the side of the road. The computer shuts my car down at 111 mph. So before I installed this part, since my speedometer was off, 111 mph meant that I was only going 91-92 mph. Now that the speedometer has been corrected I can actually go 111 mph. Not that I ever actually go that fast. ;-/

      Decent product

      This is a decent product that works as advertised. Includes a new retaining clip (Thank you!) This product is simple to install but does require access to the underside of the car.
