Scott, I was reading some older threads and saw yours about twitchy handling from a few years ago. My 73 is very "darty" or twitchy. I haven't done anything major except add a bit of play to the steering.
60 Series tires on 15" Rally's. It has power steering and it is sketchy to drive. You really have to be paying attention. I am going to take it in and put it up on a rack, just looking for someone in my area that has experience with these cars. Did you add any toe to your front? did you find anything that helped. Mine could be any number of things at this point.
