Rear 68 barracuda fast back trim

Question 1 is the Crome around the rear glass on a 68 fastback the only thing holding down glass ? I Have a 67 fastback and have not got the special one year only stripes .SO I am using he 68 rubber but have no Crome trim . Would any one have the trim for sale . ? And what would be your price thank you . P.S I am chasing these parts for a friend .
