Does anyone know where to pick up the plastic fasteners that clip the door panel to the door? As I'm sure is pretty common, quite a few broke when I was installing speakers. I believe the part number is GJ6A-68-AB1. I found some in a few places online but they either don't ship to Canada or are ridiculously expensive to ship for such a cheap part. I'm not sure if the dealers carry them because none of them have an online part lookup. Has anyone bought them locally? I'm in the Markham area.
