66 Dart GT HT Whatsitgonnabe?

I think new shafts are available if yours is cut up pretty bad, or maybe somebody has spares they can offer you.

I don't think the cuts are a problem, really. The remaining surface area should be plenty to handle the forces and the groove will be a good grease deposit, I think.

Don has all my new polyurethane bushings. They'll be on their way here soon.
