One of the 10mm bolts was a left thread. So I had to use it in conjunction with a piece from the OEM mirrors. No biggie, I'll just pick up another bolt. Except I couldn't find a 10mm 1.25 thread pitch. I could only find a 1.50.
But I had a flange head brake caliper banjo bolt which was the right length and a 10mm 1.25 tp. But it had a 12 mm hex head so it wouldn't fit into the mirror bracket.
So what I did was hand file the 12mm hex head down to a 10mm hex head and I reduced the flange to fit. Beautiful.
But get this..I screwed the bolt into the brake clamp hole to check the fit and as I removed it I dropped it into the front of the bike.
What happened next for hours was me looking for it with a flashlight and inspection mirror and an extension magnet. No luck. I had the whole front of the bike apart looking for the dang thing and couldn't find it, no how, no way. It wasn't on the floor.
Finally, the next day I was more methodical in the search. Even though I had checked around the front brake calipers the night before I finally found it lying on the front wheel hub stuck in the brake rotor. Twenty minutes filing the bolt, three hours looking for it.
Anyways, thanks for the mirrors. I sent you reimbursement for the shipping though you told me not to bother.
