Alright, you a already have a 73-76 A body, Drum brake car, that your converting to discs.
So then you have a factory sway bar on it, with the lower control arms having the mount tabs welded more or less in the center of the arm.
In that case you can mount the calipers in the stock location facing the front, without any interference problems.
It's when you have a 72 and earlier, sway bar equipped A body, that you run into clearance problems.
Sound pretty straight forward. Only I don’t think it’s a stock sway bar. It’s a 1 3/16” bar and the tabs are bolted to the lower control arms. I don’t think I have seen anything like that before. It still may work as you mentioned above.
