Were does the speedo convertor fit on an early classic is it at the clock end or gearbox end? Is it a long job fitting?

 

Depends which one you have. The gearbox side is the easy one, it just connects in line with the speedo cable. The one that goes on the clock is a bit more awkward to fit if you have fat hands . It's not a long job, half hour or so.

 

ah so there is different types. Do you have to take the clocks out to do it?
