Since I've started driving my Fury the odor of the interior is starting to wear on me. It sat in a barn for ten years before I got it and it looks like mice had been living in the headliner. I didn't realize how bad it was until I took a trim piece off and mouse turds started pouring out. So needless to say....a new headliner is now a priority here. My question is - what is the degree of difficulty in replacing a headliner in this car? Does the rear window need to be removed? Is this something I can take on myself or should I take it to an upholstery shop? I have never replaced a headliner before but if it is not worse than rebuilding the suspension then I can probably do it.
