GM part # 3718465 and 3718466. Never mounted, still in black primer. Always stored in a heated extra bedroom. I should have removed the cardboard wrapping sooner, one has light surface corrosion on top side. Tiny ding in the other. Photos available to email. $2,800 firm--pickup in NE Iowa ONLY, I've shipped this type of part before & it always gets damaged.

I don't have a computer at home so it may take me a few days to reply.
