67 Dart GT convertible moulding seals

I have had a new windshield and seal replaced on my 67 Dart GT convertible and I am ready to install the wide stainless steel trim around the outside of windshield. These pieces had some remnants of some kind of weatherstripping on the underside of them where they meet up with the windshield seal. Does anyone know where or what I would use to seal this trim?
