1973 "poverty" Duster with rubber floors - what kind of floor mats?

Hey everyone!

Doing some cleanup on my 73 Duster. It's a very base, very un-optioned car with rubber floors.

The original rubber floor is in great shape and I'd like to keep it that way - so I'm looking for some floor mats.

I'm trying to keep it as "oem" as possible - so I'm wondering if cars with rubber floors would have had floor mats, and if so, what kind of floor mat would they have?

I've seen the single rubber floor mats like these, and wondering if they would be correct (although I'm struggling to find them in Black)



Thanks!
