Trying to repair the turn signal switch in my '46, which is a collection of parts from previous owner. Best I can tell the steering column is somewhere between a 60's to 70's GM column. Tried one I got from local parts shop, didn't fit. In addition to the switch itself, the rubber bushing shown is damaged and not sure if anyone has ever tried to find one - dealer only? out of production? LMC?

I've posted a series of pics below, if anyone can make a positive ID so I can order a replacement part I'd be most appreciative.
