Aftermarket mirrors work fine.....just make sure you don't buy the "classic " style mirrors. They mount to the side of the body. The edge style mount to the "top" of the body, I'll get some pics up to show the difference. ( I screwed up and mounted classic mirrors on my edge, I wish I'd have researched a little further before I bought and put them on. ) It looks ok, but the pre-molded areas on the edge body would be a stronger mounting point OMHO!
