Well, a couple days ago I had the top down about half way, and when I put the top up again, it met the windshield properly.
In 1970, I lent my 1965 Pontiac Catalina convertible to a young guy and within an hour he ran a stop sign in a school zone, because, he said, I pickup camper was parked where he couldn't see the sign.
After that, the pins in the top were at least an inch from the matching holes in the windshield frame. For one or two years. Then they were perfect for one or two years, and then they were just as bad as before for one or two years.
So the fact that the top matched the windshield on this one occasion is encouraging.
