Hopefully these will help, RH mirror is bolted through the hole in the brake lever pivot bolt, the LH mirror is attached using an adapted pushbike brake lever clamp from eBay, unfortunately I bought that 3 years ago and can’t find the original eBay ad, it’s trial and error and you need to take great care that they don’t contact the tank on full lock, mine clear by 5mm, it’s not a lot but they can’t get any closer of course, hope that helps.
