Ok I have a 1998 Deville D'Elegance and driving home yesterday I pull my plastic sunvisor down (the one behind the cloth covered one) and it broke :rant2ff. The screws are still in the visor mount but I cannot figure out how do get to them. Do I have to take the whole headliner out (lord I hope not! :worship? I found a part # stamped into them but I haven't called my local dealer yet for a price, anyone know how much they are (just the parts)?
