65 barracuda headers help

The early Barracuda take a different header than the 67 and later A body cars. Hopefully you have the right headers. I not aware of hooker headers that fit the early "A" body. Doesn't mean they don't make them but if they do they may be fenderwell exit or partial fenderwell exit style header.

Do you have a part number or did you buy them used? If you bought them used what year and model car were they on?
