Unacceptable: tubular upper control arms with no bump stop pads.

I think B-Bodies have their bump stops in a different spot that makes it work. Even the factory A-Body arms have a flair to them to get them over to the bump stops.

Apples to oranges
No its not. If everyone knows that A bodies are different, then either engineer the part to fit, or sell an offset bracket as a complimentary add-on.
