This is a new old stock (NOS) one-piece roof rail weatherstrip for a 1965 Ford Galaxie fastback model. The weatherstrip is designed to fit the 500, LTD, and Monterey trims. The part number for this weatherstrip is C5AZ-6351223-A and it was manufactured in the United States.

Didn’t feel there was any use to remove it from its resting place of the last 50+ years but will if you need me to

Please make sure this fits your application as it is your responsibility
