    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.

    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!
