Speedometer Service CompanyRusty at Speedometer Service in Colorado should be able to fix you up. He repaired the SW speedometer in my '39 p/u. He also made a cable to connect a Ford AOD to the speedometer in my '54 Ranch Wagon. Can't say enough good things about him. He is an Alliance vendor on the HAMB.
