Hello, Deejay,
Thanks for the input. The shaft, springs, and cover all currently rotate as a single unit on the U-bracket. The inside free ends of the springs would need to be quite long to lock against the U-bracket in order to "tension up" as the cover is raised to the open position - but maybe you are correct - the springs may have been previously (modified/buggered up) by persons unknown.

I would be interested to know if new springs are required, and if so, where I could obtain them.
