It has no mounting hardware (it is out of a 90 F150) it just sat in a plastic "box" behind the glove box with the hose connectors poking through the firewall. It looks to be all alum. Didn't know if they used other metals when the make them or if it could go as alum. I will have to look closer (and poke it with a magnet). I guess my best bet would be to call the yard.
