There's a guy who works in the management team at a Northrop-Gruman shipyard in Mississippi that drives a triple white 67 Barracuda vert to work sometimes he says
His RHD A-body he said was factory & looked it.
He said that he owns a B5 notchback factory built RHD to go with the vert too
I met him at "Cruising the Coast" a few years back
