how difficult is it to replace the headliner in a mkIII? i'm doing an interior color change and the carpet place that i may get carpet from will sell me a headliner kit for like $39 or something, and while i was just going to dye the existing headliner, it's kinda messed up. i would rather replace it, but if this is not possible i'll just keep the existing one. has anyone here removed the headliner before and installed it again successfully? this is hardtop, btw.
