T-bars do wear out. I can crank mine up a couple inches and it'll settle back down after a little driving. The bolt doesn't back out.
The front of the hot rod sits level right now. The adjuster on the right side sticks out past the control arm. The driver's side is up inside the arm.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
