Hanging rear quarter panel to roof belt trim moulding! 1965 Valiant

Any thoughts on how to plot new holes for 1/4 to roof belt trim? I can't tell if this Valiant had the trim and the holes were filled or if it came without the moulding...In preparation for painting the roof black I want to re-install this moulding. It will hide the paint line nicely... But where does it actually hang? Thanks!SAM_0538.JPG SAM_0539.JPG SAM_0540.JPG
