I bought one for my 68 a few years ago (not exactly sure) when they first came out. I sent it back. It was very wavy across the top edge and the chrome didn't look all that great - although I'm not really sure how the chrome looked from the factory. I restored mine using the chrome mylar trim from Rick's.
