G'Day Bill, that reminded me of my first CB750F2 (very early days of EBay) I needed headlight brackets, my bike had been fitted with an aftermarket fairing when almost new and the PO threw away the OEM brackets, and they were (then at least) as rare as rocking horse shiit.
I never found a set, the ones that came up on EBay would go for over 100 bucks, (which I would have paid, but I didn't have a snipe program, so got whacked) DSS didn't have them, and neither did my Honda dealer. When I sold it, it still had those crappy aftermarket mounts on it.
You couldn't use any other Honda mount (I tried, I've still got several sets) because the headlight bucket was so big. Yeah, I could have changed that too, but I wanted to keep it original.
By the time I got around to restoring my current F2, I was a member here, and got a lot of help from Mike Rieck, (wiring loom, sidestand, grab-rail and some other stuff I've forgotten) Sean Condon (head, front fender, headlight ears and heaps of other stuff) JTB, and quite a few other guys, so keep asking mate, this site is full of good people, and someone will have what you want for the right price! Cheers, Terry.
