1970 Dart with no Headrests?

I will get pics tomorrow, It is just a ugly old green bench seat with original covers.
Split bench two door seat and has no provision for headrests.
Car is untouched, It still has the original tags from 1970 on it.
It is a 318 Swinger, non air and had a 8 3/4 rear.

Pics are coming.
