i have a 69 and i'm not sure what holds up the sides of the headliner. i think it's similar to a 67 with the tach strip underneith and the metal trim on the outside but i can't find either parts anywhere. but i also read about putting a headliner in by snapping the sides in with clips but i'm not sure of the year of that chevelle. i need to know the method of installation and where i could get the parts if possible. thanks
