67 Barracuda trim?????

I've changed notch back coupe from 67 OEM to 68/9 trim on 3 cars over the many years. I've discovered a few small differences in the sheet metal and bodywork at the window openings that should be considered. Factory workers didn't need to get the lines as straight in 67. Starting with 68 model the workers had to have a straight edge or similar to check their lines and they had to trim the line and lookout length of the fence that the gasket sits on. Bottom line... The later gasket and stainless trim will show off what one would never have noticed beside the 67 rubber.
