I've broken a fork and know just how much damage to me that can do. (I was lucky. I only lost thousands of dollars, years of recovery and my profession.) When I ordered my Mooney a year after my accident (Peter Mooney was a clubmate and at the club annual dinner when it was announced I was in a coma) I asked for braze-ons for LowRiders. He wouldn't. Wouldn't drill a fork blade. First 4 years, the Mooney wore the U-bolts every time the LowRiders went on. Bent that fork and ordered another. (Crash, the Lowriders weren't on the bike.) Asked again about the braze-ons. Peter said it had occurred to him that the English light/generator mounts could be used; no drilling required and that he'd be happy to do that. And they've been on ever since. I have to drill out the racks for the larger bolt but that isn't exactly hard. A round file also works.
