Is your Newport a 2dr? Was the SRT a 2dr? Keep in mind, any modern 4-dr seats might not have provision to flip forward.
In the old days, a 4dr bench was sometimes made the same but needed a bolt removed and a pin and latch swapped in.
Modern seats are made totally differently from what we are accustomed to.
They are lightweight, even considering all the electronics and features in them.
There are no hog rings, most of the upholstery is held on by elastic snaps.
And a loaded power seat can easily have 2 connectors with 20 wires in each.
I have a set of 2017-ish 300 seats and there looks to be no way to easily make them flippable.
The frame is all fabricated, formed and welded.
One funny benefit, though: Modern cars have hte cats up by the engine, so even on a RWD car the floorpan can be pretty flat.
While a car from the 80s/90s might have all 4 mounting points at differnt heights.
