Fred,
Throw it out and find a good upholsterer. That foam stuff was a mess anyway. I put a different headliner in my Cat and the upholsterer told me that the foam would cost me more to have installed. Not to mention one scratch and it's toast anyway.
Thought that I would sign up on the board. I'm new to Team Buick, but not to Buicks. I've been restoring my '63 Wildcat 4Dr. HT for almost 3 years now. There's some pics of it in my photo album.
