Can you guys verify what year these are for? I believe they are 1968 due to the manufacturing dimples in the photos. They are in nice shape and I will be selling as soon as I confirm I.D.

 

Those sure look like '68s. When I had mine out for color restoration and repair of the mounting tabs, I cleaned them up real well and inspected them closely. I found a "68" molded into each one. I thought I had pictures of them showing the 68s, but I can't find it/them at the moment.

 

I have seen date stamps on the front flat part of these. I think on the bottom surface?
