Reproduction Tail Light And Reverse Lenses 1965 Valiant or 1964 - 1965 Barracuda

Those are 65 lights. 64 has a rectangular back up light. The red lenses may be the same for 64-65.
I just looked at 30 or 40 pictures of '64 barracudas and all of them had the same reverse lens as I have here.

The 1966 model does have a rectangular reverse lens.
