Hello, can someone please tell me how the three crown-shaped mirror fasteners (clips) are made of spring steel, which are riveted to the mirrors with blind rivets and with which the mirror is attached to the bolts (part 03) on the panel. BMW does not seem to have them individually, but they may not be special BMW parts and therefore may be otherwise available. Of the six crown-shaped parts, on the two mirrors, there are some clips on three. Laschen aborted, whereby the mirror no longer fits properly tight. Thank you for your tips and help Liebe Grüße Herbert
