It looks to me like you have a Borletti angle drive. There is an alternative to a new angle drive. You can send your speedometer to a speedometer shop such as North Hollywood Speedometer or Palo Alto Speedometer and have it converted to electronic operation. Then replace the angle drive with a VSS or drive the speedo with a GPS sender and cap off the angle drive mount on the ZF. Other than eliminating the speedo cable, an added benefit is the ability to easily calibrate your speedometer.
