I screwed up, neep help

Rod, I just had the “lower” piece of trim out on my 64. The “upper” piece is screwed into the body with the screws from the trim clips. The clips go all the way around the window, bottom, top, and both sides. The “lower” piece of trim will snap into place against the rubber of the weatherstrip and the clips hold it against the “upper” trim. There are three pieces of lower trim. Two for the top that slip into each other a bit and go down the sides. One straight piece that slips into the other two and still has clips holding it in place. Again, clips all the way around. If any are missing, that lower trim will not snap into place and stay.
