Default correct heater housing valve

I've got 2 heater boxes, one that was in my car 1973, and another I bought used supposedly came from a 73. (Mine had some damage to the housing) I am not positive the one from my car is indeed original. So what I got is the vacuum valve that operates the small door, interior side heater core. The valve on the right has 2 vacuum ports, one on each side, the other only has one, and there are differences in the arms that attach the valve to the door. Any clues as to which is which, is one correct, one incorrect? And does that valve hold the door open and vacuum closes it or vice versa?

I can try to take a look tomorrow.... My first thought is the pod on the right is a replacement, the one on the left is a original (we are stirring old cobwebs in my head lol) I have plenty of used boxes, and it seems as if the one on the left is correct.

Maybe my post will bump you to another answer from someone tonight.

thanks, that was fast, any idea why the replacement one would have 2 ports, does it matter, and I could really use some help with parts (a/c included) piecing the whole thing back togeather
