This came out of a 1964 or 65 Skylark some time ago. I believe it will work on 66 and 67 as well. It's just sitting my garage taking up space. Maybe someone wants it. I couldn't find a part number on it or a date code. It might be there but I just can't find it. See photos it does have surface rust. The plastic sleeve on the backside does have a small crack. Looks to be about 8.75 wide. Maybe 9 from outside edge to outside edge. $25 + shipping from 60586 IL. PayPal friends and family or Postal Money order. Thanks Brian.
