1961 Plymouth Valiant

Searching for information on behalf of my auto-transmission guy so he can help another customer.
Who makes reproduction push button auto control cables? I am presuming he wants both (selector and park) cables. I haven't seen the car, he said the car is a 1961 Plymouth Valiant and I am assuming it is still left hand drive (we are in Australia).
Are these cables interchangeable with later cars (Dart, Signet, etc)?
