31 tooth speedometer gear

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.
