I have researched this a bit - since I am restoring a car with the 216 interior (Light Saddle). From your picture - It looks like your door panels are still correct to the 1964 code and pattern. As far as I can tell this interior code is unique to 1964 - and other years Saddle or Camel will not match.
To make things worse - the current vinyl offerings are incorrect. I am in contact with Legendary and trying to get a more correct option. Here is a picture of piece of original vinyl from an area protected from the light (center), with SMS "original" material and Legendary's reproduction.
As for dying your existing upholstery. I think you will have to have something made to match from the door panels.
Hopefully this is helpful...
