Correct name/color access discs in Challenger trunk?

There are 2 discs with screws and rubber discs on the trunk floor of my 70 Challenger but can't find/recall what the correct name for them is. Also, I remember a discussion a while back about what the correct color of the discs should be but can't find that link either. The ones that came out of my car have a redish rubber disc but that may not be correct.

Thanks, Joe

Shock tower access holes. Reddish rubber is correct.

shock access plugs
clear zinc plated steel discs and a reddish orange rubber seal

Thanks guys.
