67 Barracuda Dash Bezel

I have a push button AC controls that goes in the bezel but they do not seem to fit in the frame too wide and won't bolts won't line up (could be a year thing I don't know), I also have the orginal cable control set up from the car so the question I have is how would I control the heat when the push button is vacuum controled? I would love to keep this setup as I hope you can tell I just pianted the dash and the car should be painted by this weekend so I am planning on getting it back together soon.
