honestly its like the easiest thing to do. foggy, you shouldnt have any trouble with it. EZ did a slightly different way then i did because mine was not sagging, and i had the sunroof to hold everything tight so i didnt worry about it sagging. just unclip everything, but be carefull of the two clips in the back above the window. One of my clips is forever lost in a hole because it fell when i poped it off. Take it out the back of the car, then just remove all of the old carpet. it just pulls off. If you want to get rid of the foam like EZ did, im guessing it just rubs off. i had a massive piece of felt and got a few different typed of fabric and spray glew and wraped the fabric around the top edge and glued it from ontop of the headliner, then just slowly make your way to the back glewing and flipping the headliner over and glewing the other side. I dont have any wrinkles or anything in mine now, and ive never used fabric for anything. Just be sure to cut all of the holes for the sun visor and shit before you get it to the car, i cut all of the holes, but not big enough and they were a pain in the ass to put back in. Ill take a picture of it if you want.

Thank you mobil one for rust proofing my driveway.
