Crossland X 70 plate wing mirror unit and back cover

[ChoostyChoosty]

Down my narrow road, people speed by and often clip my mirrors when I've forgot to fold them in. So I now have on driver (offside) mirror the surrounding plastic has a big chip out of it. Does anyone know a way to repair this without buying a new assembly?. On the passenger (nearside) just the back cover has smashed off so need a new, colour coded one of those. I don't want to get a plain one and prime/paint it. Any good ideas?
