I became weary of speedo issues and installed a Speedhut GPS unit. Very happy with it- no mechanical issues- always accurate regardless of transmission, gearing or tire sizes. It did require a slight dash hole enlargement.
George, thanks for the reply. I have heard of MG owners going in that direction. I at this time am to far along to change direction. Rebuilt speedo, new cable and angle drive. I'm just trying to find the time to crawl back under. cheers
