47-55.1 Wiper switch question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm trying to acquire the parts needed for the vacuum wiper switch for my '51. Yeah, I know, get electric wipers. But I'm feeling nostalgic, what can I say. I've purchased the knob, the control rod between switch and vacuum motor and the grommets for each end of the rod but I haven't been able to find the switch assembly itself as seen in the pic below from the 54 manual. The most necessary part. Does anyone know if it's available aftermarket? Maybe there's a workaround. Any help would be appreciated. Thanks.
