Answer
Cindy,
Thank you so much for the added photo.This helps greatly,and I would say a roof replacement is
needed and not an option.
The roof panel is joined with the rear quarter panels at the top.Right behind the rear side
windows at the top.Check the websters for mustang aftermarket body parts. You may find what
you need at a great savings.
                                  best of luck and thanks again for the photo.   Bill
