Observations from My Disc Brake Conversion

Interesting point that I had not considered. But the part number reflected on my order and in the packing slip is correct for my car. Not to say they couldn't have messed it up, but they look exactly like what PST advertises on their site for the A-bodies.

I would ask the supplier how to tell the difference and compare yours. I work in Manufacturing Engineering and yeah, "things" can, do, and will happen.
