I'm going to install my first headliner 1965 Dart

Tell us now how you really feel about it. LOL I did 2 1965 barracudas a little over 20 years ago along with the 65 Valiant. On the valiant the front and back windows were removed but the barracudas I never remove the back window and it turned out just fine.
It was a tough job, but I’m glad I did it myself without help. I am paralyzed from the waist down and felt a major sense of accomplishment doing it. I’ve got a 65 valiant station wagon to do in the near future as soon as I get it back from Curtis.

He doin some work on it for you? People on here who've never met him will never know what a great guy he is.
