Some have tried making their own depending on the class. I don't think it would fool judges but it looks nice. It's worth having an original in unrestored class but for other classes the points lost may be minor. I would typically go with just a new Motorcraft and not worry about it outside of unrestored and Thoroughbred.
There may be more info on this site as to the top color. I know 84 and up were black top.
There may have been different colored tops and warranties for 71-83.
If you need more details, I can check with Chuck W.
