I have put an early flip out mirror set on an 821 so i would presume the later hand guards would fit an early one. I did it because the bike i bought had none fitted and the indicators were in the mirrors .just think the early flip out mirrors look great.....costly tho
Used the complete assembly but for some reason had to use lh bracket on rh side and vise verca. It was only way i could get them to clear cables and brake line.
