I've finally road tested my '63, and it's going to be quite a car. We completely replaced the drivetrain, and it now had a '65 P/B slip yoke in it. The speedo was not working on the maiden voyage, both ends secure. Will a '63 cable, work in a '65 transmission ? Not gonna stop me from driving, but this thing could be a "Ticket Machine" !!! Any input appreciated, Thanks...
