Darned things are near impossible to find. I've had three different QSL seats, luckily with springs. The spring is an odd ball "mouse trap" looking affair.
I've seen two different types of mounts. One was a little unstable. The one I'm currantly using was the better of the two designs.
I could pull my seat and take some photos of the suspension assembly if that would help.
The bracket is pretty simple....slides into the frame back bone tube, then clamps to the sub frame cross member. You'll lose your tool tray in the process as it needs to be removed for the mount to fit.
You could probably build a rigid mount and delete the "mouse trap" spring, or come up with some sort of alternate method.
I teamed up with a fabricator acquantance a few years ago and we toyed with the thought of reproducing some "knock off" QSL seat assemblies. He thought the spring would be the toughest thing to reproduce.
