Were there not torus shaped cups went onto the frame and the springs sat in them, then the upper part of the spring clamped to the rods of the saddle. The rod going through into the frame secured, though i seem to think they were only secured on the top of the spring.
I dont think they ever worked or were suppose to.
Try general google for some real close in shots and see if theres anything missing or if they do indeed fit over the tube.
