What helped my 46 was adding a slight wedge between 'I' beam and springs to give a bit more caster, helped in tracking better down the road. Also radial tires make for much better driving. I'd jack it up off the ground and have someone turn the wheel side to side and just look for slop in steering components and rock the wheels top to bottom to see if king pins are tight. just expect all front end components to be worn out after all these years.
Oh and don't drive on the wrong side of the road, sorry couldn't resist. Years ago stationed in Scotland the taxis would only use parking lights at night, scared the hell out of me.
Cheers
Jim
