Trim Rings or no Trim Rings? That is the question.

The previous owner installed some Mopar factory 14 inch rallye wheels on my '65 Formula S. One of these days, I need to clean them up, paint 'em, restore 'em some. However, I only have one of the trim rings. My questions are:

1) Did all factory installed rallye wheels always include the trim rings?
2) What happens if I don't use the trim rings, do I need to restore the wheels in a different manner or must I find three more trim rings to match?

Thank you. 100_2813.JPG
