B-body front end parts on an A-body??

I have the correct info on the ticket but the parts say other wise. I called performance online and they claim that those parts are interchangeable.

Not ruling it out but that's the first I've heard of it. Which isn't saying much. I'd call another reputable company say, PST and just generically ask them if those parts are the same.
