1967 390 GT smog tubes

I bought these in the mistaken belief that they were correct for my mid-68 GT but it turns out they are for a 67 390 GT with California emissions or (I think) a 67 GT500 with the 428.

There is a small dent near the branch for the #7 cylinder and the bracket that attaches to the distributor bolt has come off. Otherwise, these are in nice shape and appear to be original paint but who knows.

Asking $400 or best offer (plus shipping).
