I'm trying to find information on the correct speedometer gear to use in the tailshaft housing on the turbo 350 trans in my Nomad.

There is a 3.36 gear in the rear, and the rear tire is 225 75 15.

Something to do with rear end ratio and tire circumference I'm sure, I just don't know what it is.

At 75 mph on the Nomad speedo the car is running along at 60 mph.

Always a lot of helpful information here and I appreciate it.

Thank you,

Don Roberts
