Have had both mirrors replaced with standard glass by a glass company due to unfortunate incidents at various times. Had the first mirror fitted using the lip to hold it in, but it fell out some weeks later when the miror was bumped so had the glass guy cut and adhere the mirror in place. Getting used to the new flat mirrors took a little time but don't notice the difference now. Was a nightmare using one flat mirror and one convex mirror. Played havoc with my distance clearances of other vehicles. Do not reccomend riding with one of each. Have fixed small convex adjustible mirrors to allow wider viewing of who's behind me. Use't to the setup now. Will get OEM mirrors some time in the future, but ok for now. Cost $30 each to have the mirrors fitted.
