What speedo cable to use?

[Daves55Sedan]

I am using a '59 Ford-O-Matic in my '55 Ford Courier Sedan delivery wagon.
Apparently, the speedo cable turns in the opposite direction in the '57 and later transmissions, so it will not turn the speedometer.
Seems like what you would need is a '55 Thunderbird cable which would reverse the rotation back in the right direction, but the gear wont work in a '57 or later transmission.
Anybody else try to use a later transmission with a '55 speedo? What cable assembly will work?
