I have a 05 Grand Prix and the HUD works but just like everyone else the piece that the spring is held to broke. I can't even see the spring so my question is if the spring is not there can I buy it from somewhere? Does it need to be a specific spring? I really want to fix it and that is the only thing holding me from doing so. I don't wanna rip the interior apart until I know I can fix it. Thanks in advance.
