Since I started this resto on my 85 gt.i have enjoyed every bit of it ,but I gotta say I’m not a “interior guy”.although I will be doing most of the interior stuff myself,I’ve reached the point of the headliner install.i got a brand new headliner in the box with the car.ive opened the box and looked it over.i forgot to mention that it has a factory sunroof.which makes it that much more of a pita!my question is,should I have this installed by a upholstery pro?ive watched the YouTube lmr video but it always looks easy in 8 minute video.aldo,if I do decide to have it done,what’s a fair price?
