I just bought a beautifully restored 1966 El Camino. Just about everything works except for the speedometer. I searched the threads, but can't find any pictures or diagrams of where the cable runs for this generation, but future gens sound like they run from the back of the trans to the speedo. I don't have cruise control so assume it's a one piece cable. That said, anyone have any tips, pictures or suggestions for getting the speedo working again?
