1965 Factory Air Pulleys and Belts

I have looked at dozens of pictures on the web of 65 AC cars, but I've only found 1 picture with this cast iron bracket.

This is from a 65 Barracuda that was for sale here and advertised as having factory air.

So my first question is whether this is the correct setup for a 65 car with AC? Given the lack of photos, it seems to be pretty rare. But maybe not that many cars left the factory with AC in 65.

My second question is what should the alternator adjusting strap look like? That's the one piece I'm still missing. I might be able to fab one but I would need to know which bolt it's supposed to connect to.
