Is it possible for new gears to make the odometer inacurate. I noticed that mine has been going a lot faster than usual. Usually from my house to the school, it's 8 miles, today it said that it was 13. Damnit I've been driving like this for about a month. It probably has an extra miles now.
1: Dallas Mustang or whomever and get an electronic speed-cal.
2: take tail shaft of replace the internal drive gear to 6tooth and get the correct speedo gear.
