Dale,
This isn’t going to directly answer your question…but…
Shocks should not be used to level a car or adjust ride height. The earlier term for shocks (dampers) is far more descriptive of their sole purpose. They control rebound, when your suspension is compressed.
If the car is not sitting level, there must be some other issue going on. Difficult to diagnose that here.
That said, anyone who grew up in the sixties or seventies muscle car era, knows that air shocks were used to lift the rear. But gave a hard ride. And no, I’m not recommending you add air shocks to your TDr. You won’t be happy! Amusing aside, a prior owner of my 1965 Plymouth Satellite added air shocks to “solve” a sagging rear end of the car. The real issue was 60 year old leaf springs that were far beyond their normal life. Replaced the leaf springs, went back to stock replacement shocks, and the car rides like she was new.
