I think this may have been asked before, but I am prepping for headliner install. What would be the screws to put in before hand. I think it is coat hook (2), rear view mirror (3, rear upper trim piece across back of headliner (3?), and sun visor on each side (6). I am not going to be putting in the console, so I don't need those. Any other suggestions for the prep or are there other screws to put in before I put headliner in? Of course, I am putting them in so I can find them and cut a little X to get the screw after headliner is installed. Thanks.
