How to Replace Sunroof Handle Crank

[Learning]

Hello,

I was driving and suddenly the sunroof handle crank fell off. I saw some broken parts around the center of it. Where can I get the best price for this part and how do I replace it? Hopefully, it won't be complicated.
Thank you.

Pardon me, but what has this got to do with an M42 engine?
