The difference in '67 HO GTO manifolds & the '68 GTO HO-RA manifolds, is the position of the drivers side outlet. the outlet is slightly fwd on a '67. If anyone has a loose '67 drivers side manifold or an early repro, & they have a tape measure & can post a picture, can easily mention where to measure. Can even pull out some original round port manifolds & make comparative measurements.
As I mentioned in your previous thread '66Sprint6, I've personally examined the remedy to a similar problem, be it decades before Paul D came out with round port manifolds to fit in the '64-66 or '67 A-body frames.
