I just wanted to check whether yours didn't have the header clearance bump. The other one I looked at (yellow) didn't have it either. I think its something they added when they made the new molds in the summer of 66.

Chris, all I can say is what I'd do if it were mine. I'd fill the holes, try as well as I could to match the metalflake and color and go with some chrome bug tail lights.

I'll try to find my pictures of the yellow one to see if it had the Z brackets, but I think it did.
