Sprung solo seat mounting?

I'm planning to mount a spring type solo seat on my chopped KZ750H3. Not sure how to do this (though I have some ideas). I'd prefer to do it without welding. The seat section of the frame is stock. Has anyone here done this, and how did you do it? Thanks!

I am also using a spring solo on my kz650 but it will be welded, while searching for the hardware I did come upon bolt on mounts on ebay. I just searched solo seat mounts under the motorcycle parts tab. Hope this helps.

They have either a bolt on or weld on type solo, may be what you're looking for.
