74 dart swinger vinyl top

I have a 1974 dodge dart swinger.
One of these days I need to tend to some issues under the factory vinyl top. Here is my problem I need help with. I really want to put a factory looking top back on the car same color and all. I'm having problems finding the correct green top for the car. I can find white and black. Do I buy one of those and have them stained or can you buy a color matched one.
Thanks for your help everyone.
