Whatever happened to the Dodge Diplomats?

Yep, no coil springs. The twisting action of the bar is what keeps the suspension loaded. 

My '04 Ford Ranger 4x4 is the same way. It has torsion bars. I cranked the torsion bar bolts in to bring the front height up to match the back height after I first got it.

About the only thing you could have used was engine and trans ,,and maybe the disc brakes

My foggy recollection of them from the time was that they were prone to transmission failures. It was lore that made their resale values plummet. Mopar fans might refute this, but that's how I remember it.
