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.

    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. ;-/

    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!!!
