What is the difference bewtween the side moldings for a 68 or 69 SS. Is the molding a different
pattern or size?

Hey ctrain, You made a real car out of this old SS again. I don't know if your aware of it or not but most of these had one piece front windows starting with the '68 model year. I used to think all the '68s had Astro ventilation but have seen several like yours with vent windows lately.

Yes, that's a nice job!
The 69 SS didn't have the side molding, the Malibu did. I'm thinking that the pieces are identical except for the rear lower quarter panel is shorter on the 68 (the rear bumper angles in on 68 and the 69 is straight up and down)
