1966 Dodge D/Dart ~ 'Mystery, Myth and Misconception'

Alan,

They could be OK Kustom Headers {Flint, Michigan}.

They were fabricated with 'Large Primaries'.

And, they were notorious for improper bends. They hit everything and did not
fit worth a damn.

They do not look like the 'fenderwell' Hooker Headers my Father had on his 1967 Barracuda 273.
