I have a 71 El Camino with cowl induction. The drivers side wiper arm doesn't work. After pulling off the arm we discovered that the threaded nut that attaches the wiper arm to the transmision arm is rusted out and the treads are striped. All I need is the threaded nut(bolt)that attaches the two together. I'm being told I need to buy a new transmision arm.(which I can't find) The passanger side works and the motor works.

Hopefully someone can help.
Thanks

Park style or hidden style wipers? The transmissions are still available out here. Don't think these are reproduced. Send me an email. Think there's one in the garage.
