Windshield Mylar install Question

VALKMAN, I'm listening in here. My '67 Valiant's windshield and back window are in good shape. The rubber seals look okay but the mylar strips are falling apart. Also, I'm missing most of the stainless steel corners and joiner pieces.

The shop manual is not real clear about the following:
- Is the rubber weatherstrip all one moulding or is it in two parts?
- Does the mylar strip lock the rubber weatherstrip in place?
- Can the mylar be replaced without pulling out the rubber and glass?
- Will the glass stay in place if the mylar is pulled out?
- How are the stainless pieces fastened?
- Are the mylar trim and these stainless pieces available?
