factory black on red interior

You can be fairly confident that black was as rare in 70 as in 71/72.
It was the least painted color for Valiant/Dusters..

Ive seen a couple 70-72 black dusters and ive only seen 2 with red interior which only one of the 2 exist now.just thought it was really rare and was hopeing there was a way to find out how many was built with red int..guess not.
