I finally took the time this weekend to work on my 61. I had the instrument cluster out and managed to get all the electrolumecent gauges working except for the part that lights the transmission selector buttons. The repairs mostly consisted of soldering a few tiny wires that supply power to the gauge needles. My speedometer is not working also, the cable and speedometer head are ok but I have a problem at the transmission end of the cable. I need to replace the part that goes into the tranny. I think maybe the square hole is rounded or maybe there is a pinion or something inside that needs repacing inside. There is a large nut on the side of the tranny but I did not have socket big enough to remove it. Does anyone know what size tool I need to remove this thing? What part do I ask for? Is it sold as an assembly and are new cables available? Frank
