1960 through 1963 GMC used hydraulic clutch.
They went to mechanical in 1964 to 1966 (and beyond)
Master cylinder, slave, and bell housing are all the same all those years. Bell housing changes when it went mechanical in 1964. Hydraulic slave/fork on the passenger side, mechanical is on driver's side.
*Note* auto parts stores will try to sell the Chevrolet single cylinder so I -assume- that 1963 Chevrolet's were mechanical. There were a few differences between Chevrolet and GMC for these years.
At least for 1000, 1500, and 2500 series trucks.
At one time I had one of every year. And variety through those three series.
