RB gearbox speed sensor

[RB20DET Silvia]

Does anyone know if the rb20 gearbox (in any vehicle, manual or auto) came out with an electric speed sensor? Or if any other RB gearbox came out with an electronic speed sensor? Or if any electronic Nissan speed sensor will fit into an rb20 gearbox?

The reason I am asking is because I need my silvia speedo is electric where as the rb20 gearbox had a mechanical speed sensor in it.

We can supply a elect box that will convert the mechanical to electronic signal to run most speedo's

Or you could just pull out the machanical one and stick the electric on in, they interchange. Count the teeth though to be sure you are not going to change the gear ratio driving the speedo. If they are different you will need the gear from the inside of your original transmission as well.
