I'd like to convert my 242 to use the newer style electronic speedometer that uses a tone wheel in the rear differential assembly to read the speed. Does anyone know if I can simply install the tone wheel on my existing differential and replace the cover with one that has the sensor? Failing that, can I swap in a differential that has the tone wheel without a lot of screwing around, or is it easier to just swap the whole axle assembly?
I realized in thinking about this recently that the rear axle is quite possibly the only part of a 240 that I've never disassembled.
