I'm restoring a 72 Chevelle Convertible. I am using a Goodmark replacement quarter panel for the passenger side.

What is correct for the transition from the quarter to the filler panel? Should there be a visible seam/crease, or not?

Well, I've got an original 63,000 mile 72' convertible the shows the seams on each side, if that helps....

Although for 63,000 miles, it sure has a lot of undercarriage rust :D . I'm addressing that now.
