TTI Shorties in an Early-A?

You've answered your own question by calling the header manufacturer. They told you they don't fit and they will not if they're designed for the 67 and up cars. They won't fit. Keep asking until you get the answer you're lookin for, then order them. You'll find out they don't fit. The Spitfires, Sandersons and the modified Hedmans are the only ones that will fit. The Hedmans only fit modifying one tube on the driver's side and without power steering.
