Re: Speedometer match between 1939 speedo and 700R trans

You're having to match the rotational speed of the cable to the speedo to give the right reading.
Some have gears to change some won't ever be right.
If it's an electronic model you can program it for wheel size etc. You can have the speedo upgraded to look original but modern electronic guts top match. Just how much you want to do to get an accurate speed. I'd talk to the suppliers and let them figure it out.
