Guessing the natural inclination to tinker was too much for the guy.

To take tires out of the equation, ride height's measured from the top of the wheel arch [sheet metal] to the bottom of the rim loaded normally on a level surface. I do mean level - more than 1/8" diff wheel to wheel is a big problem; I take pains to have no diff.

I noted the number of threads above the gold collar, rear springs, had been changed:

A few pulls on the spring wrench - tighten clamp w/hex key - my broke ride transformed to new hotness!
