speedomter 'corrections'

[woodsnake]

I have 3. 89's in my 69, and am having a hard time figuring out what drive and driven gear I need for that ratio. Any suggestions?

Maybe here.... TCI - TECHNICAL INFORMATION: Speedometer Gears ....or any of the sites when searched. There are a lot out there....just find one you can work with.

If you're running an automatic transmission, you'll need either a 21 or 23 tooth driven gear. The drive gear is cut into the output shaft and can't be changed. If it's a manual, then it will have a plastic drive gear that will give more choices for picking the driven gear. Go to Mustangs Unlimited's site for gears and the calculator.

Thanks for the TCI link, that is a lot of good information!
