You are correct, they did not especially want to snake a speedometer cable all the way from the back of the car. There is a location for a mechanical speedo take-off on the manual transmission, but it is in the area of the ring gear. Since the ring gear was flipped over in the transition from front to rear drive application, the back side of the ring gear is up against the take-off point. Therefore, the pick- up point is plugged in the DMC application. I've never looked at an automatic, but I'd bet that it doesn't even have the pickup point since it was a more "custom" transmission than the manual. As an aside, BMW has been using electronic analog speedometers (driven by the rear differential) since the mid-80s. Perhaps there is an idea for a creative car-crafter - use a BMW electronic pickup somewhere in differential area, and electronic speedo to get rid of the mechanical stuff once and for all. Another project that would undoubtedly cost all out of proportion to the net worth. Another interesting tidbit (sorry, I HAVE spent way too much time thinking about DMC speedometers) the Lucas speedo angle drive on an MGB is identical to the DMC drive (from outward appearance) but lacks the flexible input shaft since in an MGB it hangs on the transmission. Interestingly enough, it costs about the same from an MGB parts supplier as the DMC folks charge. A lot. Dave Swingle > Mike Loasby answered that one at Eurofest. I can't quite recall...
