Smoother ride? Suggestions please

[lgarbz]

I have a 1974 Plymouth Duster.
Most of the ball joints and control arms were replaced recently as well as the shocks.
It still seems to be a little bumpy when driving.
I realize older mopars aren't going to be the smoothest rides as far as handling and suspension, but I'm wondering if I can do anything to improve it.

The shocks were replaced, but they are still just stock.
I was wondering if their were some higher end shocks that would help?
I also raised the front a little which seemed to help.

If you have any suggestions, please let me know.
Thanks

Your smoothest ride will probably come from a stock suspension. What tire and wheel size are you running?

I believe the wheels are 14" 5lug on 4.
But I'm trying to find 2 rear rims that I can put wider tires on.
