    didnt fix problem

    it was delivered quickly and install was easy, but it did not fix my spedometer issue, it actually made it go up by 5mph on the guage. i got 3.73 gears and rebuilt the rear but cant seem to get my spedometer guage to reflect the right spped, it will say im doing 90mph when im only doing 70ish. dont get me wrong the part is just fine, and american muscle, you all are amazing and provide great service, i just cant figure out how to fix the issue.
