Hi, I dropped my Honda sp 150 and my brake lever and side mirror is broken.

I have tried looking on taobao, Lazada for cheap replacement, but can’t find any.
What kind of size of brake lever should I be looking for?
What after market side mirror can I install on my bike? It has only a single screw hole
On the fairing

And my handle grip is loose, does it use glue on stick to the handle bar?

Many thanks
