Sounds like an interesting project although I've never heard of anyone actually doing it.

The mechanical linkage from the head could theoretically be used to turn an optical encoder to drive the tuning of a modern radio via some intermediate black box circuit.

I bet it could be done but I don't have enough brains to figure it out! I'm old school. I'd look for an original radio and feed FM/Ipod to it via a little transmitter laying in the seat
