1966 Barracuda taillight lens
As stated, the housing, hardware and gaskets are the same between the valiant and barracuda. The middle and bottom lenses are different but interchange. The middle (reverse) lens is a little tougher to find complete
Barracuda - middle lens is white with a reflection bar - it is repoped but pricey over $120 each
Barracuda - bottom lens is red versus white
There are reproduction gaskets, I was happy with the set I used
Good luck, sounds like a couple people, including myself have what you need
