After some study, it is clear that there are two places where reinforcement are used for the quarter.
- Between the inner panel just after the jamb and the outer quarter skin. This essentially boxes the quarter window region and stiffens the attachment area for the seat/top frame.
- Between the two edge of the quarter panel and the gutter. This stiffens the entire upper edge of the quarter under the hockey-stick trim.
Looks like I need to try to locate the left/right sections of the gutter. I already have the center section.
This video shows removal of a quarter from a 67 Mustang convertible and verifies the attachment. I guess that cutting with an air hammer confirms detachment. But whatever!
