You always pic up on the weirdest things John, but shows your general attention to detail. :bash:
In regards to the rear handles, with my wagon you have to open both back doors to get the rear seat right down, or it fouls on them on like a 30* angle. However.....mine is a later wagon (79-80 IIRC), so don't exactly see how it could be a verision.
Doesn't appear to be extra holes in the door trim, so somebody hasn't retro-fitted them. Maybe just a trim option!? :y:
