My passenger side mirror is wobbly because one of the white pieces that snaps into the back panel came out. This is the 3rd time this has happened to me. The first 2 times I brought a new mirror w/ the back panel but I'm tired of spending $50 for a new mirror every time. Does anyone know the name of these pieces and where I can get them? I'd much rather pay a few bucks for the connector if possible rather than buying a new mirror replacement every time. I uploaded a pic of the pieces that keep coming out and the panel for references.
