I've got a quick question that I wondered if you can help me with. I've got a KPH Speedo in my 1959 Beetle which works fine. Hovever I recently bought an MPH Speedo to use instead. The MPH Speeso works fine to 28 MPH,then doesnt go any further. When you stop the speedo bsngs back to the stop. Would you be able to take the MPH Dial Face and put it onto the KPH backing.If so is there a lot of work needed,any advice much appreciated.
