Oh! A 124 actually is align-able. I'd start by getting the camber evened out. I don't think that is the issue though but you want to remove that variable to get to the root of the problem.

One thing I like to do on problem cars is shut off the engine and put it in neutral on a long straight downhill stretch. Careful to not lock the steering, of course. This will show whether the car is being hydraulicly steered by the P/S or not.

Another thing to look at is the spring perches. I've seen a few (and owned one) where the perch starts to rust away from the chassis. Steering geometry gets wonky when that happens. IIRC you're in AZ so that's highly unlikely but worth looking closely where the perches meet the body.
