Swinging Dart

I came across a Dart Swinger yesterday for 1000 bucks, my friend
knows the owner of the shop it is at and I'm going to take a look
at it this afternoon. I drove by it, but the shop was closed and I
could'nt talk with no one. It looks pretty straight a Calif. car, the inside
was worn but not tore up.
My question is: Did they make Dart Swingers all the way through
1976, or just from 69-72. I'll keep ya's posted if I pick it up.
