Boy that will relieve a lot of stress. Knowing that the headliner is called Regal Headliner - Whisperwall is a huge step in solving the removal/install problem.It might be easier than you think...but not simple. There's a lot of videos around about removing some/all of the 2000-2010-ish headliners in Hunters, but here's one thread with a decent video and advice on the tool to use. Short answer is the headliner is probably pushed into a trac and can be removed if done carefully.
