I have obained a Doug Nash overdrive unit for my C-6. It has the tailshaft housing and the OD unit, but not the wiring, the relay(s) or the switch.

1. Can I obtain a suitable replacement? (anyone got an original set for sale?)

2. Where can I obtain a wiring diagragm? I can probably wire one up if I have the right schematics.

3. Any advice is appreciated.

 

Not sure on this, but I have heard that the US Gear overdrive unit is a mutation of the old Doug Nash unit. Might want to give US Gear a call.
