What year of car are these headrests for?

Was wondering if anyone could tell me what year of car these headrests are for. Guessing they are for a bench seat.

Looks like 1970 & up bench seat head rests.

That is what I thought. Early 70s bench headrest. I was going to use them for parts and make headrests for my 67 300.

First pic straight on I thought late 60's. Second pic and seen the curve in rear section I got say 70's.
