Need help with Dart belt molding installation

I am going to be adding a set of belt moldings to my 69 Dart which didn't come with them originally. I could use some help regarding what the layout/spacing of the holes on the top of the doors and on top of the quarter panels along side the rear quarter glass should be. Also, I need to know what the diameter of the holes for the retaining clips is. If anyone can provide me with this information I would appreciate it very much.
