Yep had em in Jackson,Ms. before the plastic ones came out. It was in 1975 the year before I graduated. Glad that Swinger had a 318. It was light and pretty fast. You had to be careful, they would take a mailbox completely off of the post but if the bottle broke glass went everywhere. What made the Swinger desirable besides being pretty fast was that it had a sunroof. You could stand on the front seat and get a good line of sight and leverage.
