Headliner and sail panels $99 from Bob. (almost positive on price) Matter of fact Chuck Grimm ,the guy doing mine, recommended I buy the kit from any reputable dealer. Knows of Camaro Specialities, so I got the ok.Not sure if the rear window needs to be out to ease the installation.
Have not had it done yet, he's a few weeks backed up and I have just been to busy this summer to play with the car.
Sad thing is I have 1 hole the size of a quarter were a mouse got in years ago ,in the rear panel .Other than that it would present as new.
