Really tall back seats in '69 Coronet R/T, are they original?

[69_CoronetR/T]

Hey all, I've been wondering for a while now about this 1 seat that came in my coronet.

It is a really tall back seat, which I've never really seen before.

What I'm wondering is whether the short seat in that picture is original or the tall one is.

Its a bucket seat car, non console, auxiliary seat if it matters at all.
