Electronic speedo?
I have an electronic one from Auto Meter with a device that attaches on the transmission where the cable would normally go.. Hooks up by wire.
Calibrate by driving along a certain distance , by pushing a buttom on the face of the speedo.. Easily changed for any gearing or tire change.
