The change over was common in North America in the early sixties and I believe originated with the necessity/simplification of operating a clutch system for van type with a semi cabover condfiguration. Brake pedals had already changed over a decade before from solid linkage through the floor to a firewall mounted pedal attched directly to the master cylinder in the engine compartment.

The simplicity (until you have to bleed the darn system) of the hydraulic clutch linkage, allowed them to instal it on the right hand side. Once configured for vans the same concept was kept for pick up trucks.... not sure about the heavier Chev/GMC model. With the advant of automatic and electronically controlled transmission.... mechanical linkages are a thing of the past.

I need the part # to see if I can track one in our neighbourhood for possible future use....
