These often break from getting brittle from age, So i made some up if anyone needs replacement sets, I added a pic of the moldings there needed for in case anyone needs confirmation. PM me if interested and advise location for a shipping quote.
Good Job! You are right, they often get broken because there is no info in the repair manual about how to remove the moldings, and so folks attempt to pry them off. You have to remove the center post trim on the inside, in order to remove the center post trim on the outside. Then the moldings slide forward and off. Installation is the reverse.
Do a search, as there is another recent thread in which someone is looking for these.
