Alan,
Is your speedometer not functioning?
When I started driving my 1941 truck on the road, one day the speedometer began making a very bad screeching sound. Once inspected, the fix was quite easy requiring only one drop of oil. The truck has seen thousands of road miles since with no issues. Check out his tech tip as it certainly helped me out.
