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!View attachment 1715305369 View attachment 1715305370 View attachment 1715305371
Pull back the headliner on the sail panel. There should be some holes that were bondo'd or welded shut. That will be the starting point.
If filled, use a sharp pick to locate holes, then work from outside to minimize damage to paint and filler. Pics are 63 Valiant, but should be similar.
That actually looks like a 66 molding.
