How to deal with HT bad seals between front/ quarter windows?

The thing is, does the "new " one come with the chorme/stainless peice then , can the old one be unglued and new glued back on? Im talking about the 72 on back piece.
The metal piece between the door glass and the 1/4 glass is stainless not chrome. The stainless piece is held to the edge of the glass with "glass setting tape".(and on my convertible, it's also riveted to the pot metal glass retainer) The rubber seal is a separate piece and can easily be replaced. It just slides out the bottom of the stainless piece. The new seal will slide in...no glue needed.
