Sppedometer/Odometer corrected

[Tbruz]

Found a company in Omaha, Service Express Co, that made a speed ratio adapter for my 1972 Blazer.

No need for gear ratio or tire size.
Went for a 40 to 50 mile ride and then called in my indicated mileage off the odometer and the actual miles traveled from a friends GPS. The company was able to make the adapter in two days for $65. Goes between Xfer case and speedo cable

The good news is I can trust the speedometer. Yahoo
The bad news is I can calculate my MPG. Ouch

I used my GPS with the Jimmy and even with the 33x12.50's it was still less than 2 mph off at 60!
