Isn't there a Monroe Sensatrac in the right dimensions? The Sensatrac has a groove in the middle of the cylinder that allows for greater oil flow in the more-or-less center position, resulting in a smoother ride on good roads. When the road gets bumpy or the car leans and the shock piston moves towards either end past said groove the shock gets tighter resulting in a firmer ride under those conditions.
I don't know about the Monroe Sensatracs. In my searches, I didn't see them listed. In fact, there seems to be a general dearth of available shocks for the rear of '73 Chryslers. I like the KYBs that are installed on my '66 300 coupe so much, that I really wanted KYBs for the '73. We'll see what the Shocks Surplus guys have to say. Basically, I need a shock that is at least 25 inches long - extended.
