I am new and just registered. I have read several postings on this topic but still need help. I am attempting my first headliner install on a 69 firebird. It has the metal rod bows and center clips. I cannot seem to get all the wrinikles out. I purchased a headliner kit (ribbed pattern) . No instructions. The front is tricky as it gets tucked under a metal strip and screwed to the roof. It must be done first. Anyone have any tips?
