4 door windshield trim on a 67 Barracuda?

The difference in the A-pillar sticks is exactly 1.5 inches.
The difference in overall fit and finish is in the 67 body. The glass bed is a little larger so the stainless doesn't overlap as far when its put on a 67. The trim you have is surely blemished at the original overlap and if you dont polish that blemish away it wil show.
You're probably going to find the seam in the A-pillar line isn't worked as straight as the trim either. It didn't have to be perfect in 67. Likely will be a little gap there unless you redo the bodywork to a straight line. I doubt anyone would notice this little flaw unless you point it out though.
