Hi guys - just posted a hello and couple of pics in general section. My new to me 1989 (1 owner 50K ) but tatty Pontiac Safari has the GM headliner sag. Rear view mirror view is the saggin blue bag of lining hanging down-not good. So before i tear in and break something what hardware needs removing to get the board down without tearing it? Ie how much or all of the plastic/ lamp / etc and any advice? If theres a link to GM specific photos all the better. Also the safari wagon has metal trim surrounding the wood- How does this remove without breaking the clips? thanks in advance guys
