I am at a loss for repairing or replacing the turn signal and headlamp stalks on my 68 365 GT 2+2. The original handles were not with the car when purchased. The bases are still in tact inside the steering column switch assembly. I have removed the bases with the switch contacts and could likely machine replacement plastic switch bases, but am at a loss for the metal shafts and plastic handles. Any suggestions out there or maybe some left over parts?
