the headliner in my crew was the only thing that was worn on the whole truck when I got it.... and I discovered that there was no way to get it out since it was bigger than the door openings (in my case they must have put it in before the windshield was installed)... not wanting to remove my windshield I cut it right down the middle
since you have burb you wont have this problem... you should be able to bend it sufficiently to remove it without breaking it
then I researched replacements... covering,,, having it recovered.... and decided it was best to tackle on my own.... my headliner was fabric over foam... the fabric was ripped and had some holes because the P/O was a smoker (deathsticks for stupid people) and that ate up the foam...
so.... I tore everything off down to the molded carboard... repaired any tears in that with ductape on the back and 3 m spray glue on the front (I think its 777)dont use cheap glue... it wont take the roof heat and or will melt the foam/cardboard... 3m specifically details what their glues can be used on
then I thought ... I have this all down let me insulate the roof better.... soooo I used some foil bubble insulation (comes in 4 foot wide rolls) cut it to fit and then siliconed it to the roof....
I went and found fabric I like in my case... or should I say in my wifes choice, we selected a disney scene (mickey mouse... dont laugh it looks totally custom) that was color coordinated to the truck.... We cut the piece oversize and sprayglued it to the molded cardboard... making sure the edges wrapped over the sides of the pattern by and inch or so all the way around....and that it was nicely adhered to all the bumps of the headliner
then we reinstalled it and added a couple of hi intensity dome lights while we were at it...
so... for an investment of about 30 dollars we now have a totally custom headliner that is really quiet(this would also really help the burb)...definately took out a bunch of the cavernous beer can sound crewcabs have...looks sano... made my wife totally happy to do a k project together,,,, and made me realize I will never let anyone do my interior again... it was fun and easy
