GDADs51 you are right. I had checked the tire rotation and got a reverse rotation on the wheels. There are two things that are confusing. One is the test for ratio. With one wheel on the ground I get one complete rotation of the drive shaft with only 2/3 of one rotation of the tire. The other thing is what's causing the speedometer speed indication to be so wrong.
The H at the end is a different font type. Much smaller than the rest and not in line with the other numbers/letters.
As stated above the teeth count on the speedometer driven gear is 20.
