Replacing mirror

[GrinchKing]

Just noticed earlier this week that the plastic piece underneath the mirror on the right side of my model Y is missing. Some wiring is exposed but covered from rain. Reached out to TSC to get it fixed and discovered they replace the whole mirror for the cheap price of $430. I’ve located the missing piece in the depths of the Y trunk (bought the car used) but it won’t fit back on. Any ideas how it attaches back? I’m tempted to duck tape the plastic piece on bc $400 seems expensive to replace an otherwise good working mirror. Or do they make an aftermarket cap that fits over most of the mirror?

Instead of duct tape, would it be possible to superglue it in place?

I’ll look again, but from what I recall their aren’t a lot of areas that share surfaces for glue to work. Almost looks like some tabs have been broken off.
