Looking for new turn signals

I bought a set of superbike bars for my kz750 but now i don't have room for the bar mounted turn signals. I could go through the trouble of making my own brackets, but i was wondering if anybody knew of turnsignals available that would clamp to the 39mm forks. A set of just mounting brackets runs $55-$100 so maybe a set from a different stock bike?

cte10, I had the same problem when I went to superbike bars. What I did was mount my new ones on the down tubes where the reflectors used to mount. But I had to ream the holes out to something like 5/16" or so. I also used rubber grommets on the signal shafts to help dampen the engine vibrations. Then I used loktite on the nuts, so I didn't have to tighten them too much, also to keep vibration to a minimum. But now I'm working on changing my bulbs over to LEDs, which are much more vibration resistant.
There's all shapes and sizes of signals on E-bay to choose from.
