[SOLD] 31 tooth speedometer gear

[physixx]

I have a used speedometer gear for sale. It came from a 1967 Barracuda with a 904 trans. It’s green, has 31 teeth and all the plastic teeth are perfect. According to some speedo gear charts, this will give an accurate speedometer with 3.23 gears and a 27 ½” tall tire or with 3.55 gears and a 29 ½” tire. I’d like to get $15 shipped to any US location.

I am interested, but need some info ,is the color of the gear what determines the gear ratio, I think mine is blue and came stock with the Duster ,now it has 3.55 gears and 29.0 tires . My speedo is about 20 mph off at 65 mph

Yes. The color generally indicates the number of teeth but it is also indicated on the plastic part. It looks like this might be the speedo drive gear that you need based on the rear gear ratio and the tire diameter.
