1970 Duster trim

I am trying to install my A pillar molding, quarter glass panel molding and the metal pinch weld molding that goes between them. can any one tell me the correct way assemble them. I tried to put the A pillar and quarter glass molding on first and that does not seem to be the correct way! I did not take this car apart so some help would be nice I do not want to break the plastic A pillar molding's! To anyone who has read this post! I want you to know that I have figured it out and when I figure out how to delete this post I will. thanks Bill
