I'm close to that point on my truck too.
I don't remember if it was here or over on the /6 site but I need to dig up the pix of "my68barracuda"'s truck as I remember he had pix of just the ac installation posted somewhere. I know that he used the brackets for the air pump equipped version, I think he put some kind of adjustable idler in what used to be the air pump mount area.
I want to be able to use the factory AC hoses for simplicity in parts access when I do my retrofit
