I need to replace the headliner in my 2011 Civic. It is falling due to the padding deteriorating and rotting. Have seen plenty of posts about how to remove but none that say where the best place to purchase replacement material is. I want the factory color (code is warm gray) and type as this is a bone stock car and staying that way. Where is the best place to purchase factory replacement headliner material? Any and all help is appreciated. Thank you!
