Kinda like rebuilding a Quadrajet Carburetor (you don't). Toss that sucker and get an nuddern. I tried to get one out of a 68 and ended up ruining it. I'm sure there is a way to get it out, But I don't know it.
Yeah. I agree. Headliners are cheap. Upon removal, The glued ends will probably tear. When you take it out, be careful with the bows, bow clips, and keep track of how the sail panels come apart.
