Pulled the old headliner out of my 1972 cutlass "s" a few years ago. Am in the process of a full restoration. It is time to install the new headliner. There is a very good chance that the bows were mixed up when removed (also each bow has multiple locations that it can be installed. Is there a way to verify the location and placement of each bow?

 

only way I know of is trial and error test fitting the rods to see where they fit the best!I can take measurements from windshield back to each rod if needed!mine is a 70 but should still be the same spacing.
