Blackwing as in the factory or optional SLP lid???
If so, that's one I would like to find someday. The SLP lid I have on our other SS is the aftermarket SLP lid that anyone can buy. It's a little tough to get it where it belongs, but works fine once it's there. But the neck rubs the bottom of the hood, enough to rub the paint off. I just wish the neck was a bit flatter in that area. But it's too late now.
