I recently buoght a 67 GTO project that is missing a lot of parts. I've started looking for parts and am not sure what is the same for 66. Are the head light bezels the same? and is there a difference in the left and right side. Are the front seats the same or at least the shell if I recover them with the 67 pattern? Is the front radiator support the same as 66? I see a bunch of 67 parts like clutch pedals say one year only when I'd think those are the same.
