how is the weather stripping attached to the bottom of the doors on a 94 ST? the fasteners look like plastic rivets or something. am I correct? either way, I need to remove the weather stripping. What's the best way to do this? do I drill them out like a metal rivet? do I pop them out w/ a pry tool? If I have to destroy them, how do I avoid leaving little peices of the fasteners inside the door (I don't wan't anything rattling around inside the door frame)? Thanks.
