The attitude of the way the car sits reminds me of my 73. The problem with my car is not the front end, but the rear. The rear leaves are beginning to develop a graceful S-curve in them. (Under control, new McVeighs going in when weather cooperates.)
Thanks for the photos. The first thing that I caught is that there is no bump stop on the upper control arm. This means that you'll get a bit of a jolt when the suspension goes to full extension (raised car body). It doesn't look like the tubular arm would work with the factory bump stop.
Those are not stock rubber bushings in the upper control arm. I've seen polyurethane bushings that used flat washers to save wear on the bushing ends. I'm more inclined to think that the PO put in solid bushings in that control arm. Either way, the car ought to track well but transmit all sorts of road irregularities through the steering wheel.
32 psi on the tires is also helping transmit a lot of the road into the body structure. Mopar never imagined anyone stuffing a 225/60-15 under a road going A-body. Check to see if the tire is wearing more in the center than the edges. This is a definitive sign that the tires are over inflated, or that the rim is too narrow for the tire. I'm running 205/60-15 on a 7" rim @ 30 psi on the 73. It seems to be working okay for now.
Roads here are crap, too. Good luck in solving your ride/handling balance.
