Hey, Dartguy340, if you have one, I can make you a smokin' deal. I own Bebop's in Blaine. Not only will I be happy to buy the cap, I can buy you dinner and a beer or two! Coon Rapids is just up the street.
Get outta here! What's your name? "Wild Bill"(your dishwasher) never told me one of his bosses has a Dart...I had 8 of them up until this July, and have known Bill since 1975!
Back to the cap...slantsixdan is right, the cap you had on was not original, did yours look like this one?
Let me know.....Steve
