Update

A while back I twiddled with the adjustment screw, it seemed to get a bit better.

Yesterday I took it to a local shop, and he test drove it and said it feels like alignment, too much toe. Unfortunately, he doesn't have an alignment rack, so I'll have to take it to a shop in Columbus.

Reminds me of the trouble I had with an 86 dodge diplomat: not everyone can align these older dodges with the torsion bar suspension.
