I have one from a 67 A-Body and it is steel, not aluminum. I have no idea where I put it to get a picture for you, besides I am at the Nats anyway, but if I see one there I will take a pic.

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
