Converting modern transmissons with electronic speedometer drive sensor is a problem when you have a good old original cable driven speedometer.
I converted an 89 T-5 5spd.(electronic speedo.) into my 47 Chevy. Did not want to mess up my perfect original Speedo.
Nevada Speedometer, Sparks, NV (775)358-7422 had the answer!
Called the "Cable X" coversion box from Abbott Interprises, INC. The unit runs from the signal produced by the transmission sensor and turns an electric motor in the box that drives the speedometer cable. Dip switches sets up the calibration. Box mounts inside the vehical on the firewall.
This thing works GREAT!
The cost was $300.00. Electronic Speedometer conversion was alot more, a long wait and would not match up to the rest of the dash.
