Hi ya,

Well yes you can replace all the fastners, but there aren't any really except for screws that keep things in place. You may have broken window guides which are easy to replace, and these screw into the door. If you open and close a door at a time you can tell if it is broken by it rattling. I have used myself sound proofing to get rid of the trim rubbing against the bodywork. Anyone of i done of the centre dash is to use black insulating tape where plastic rubs plastic. Another place to look is where the trim meets the dash at the windscrean.
