1967 Bench seat headrests ??

Clair took the ones pictured above out of a '67 Valiant with split bench seat.

So that would be a yes for headrests in 67, no?

I actually got all the hardware/small parts pictured to add headrests to my 67 bench.
I either couldn't find headrests or didn't continue down that path, and upholstered my seat, but I keep thinking about adding them.
