Dennis,
I think that I struck gold tonight. I found what I would describe as a perfect replacement for your control, on one of my old parts radios. The shaft length and everything else appears to be correct. So, what I would like to do is mail it to you, no charge and when you have it installed, you can mail me your old one. Then I will do a photo essay of the repair of the control. If you Email me your address, I can send it off within the next few days.
Fred
