Master Cylinder Bore Diameter for '72 1/2-ton 4x4

The master cylinder on my '72 Chevy 1/2-ton 4x4 is leaking so I went to buy one today but the auto parts store doesn't know if this truck should have an 1-1/8" bore or 1-1/4" bore. Both have to be ordered so I'd like to get the right one before I take things apart. Anybody know which one is correct for this truck?

My current theory is 1-1/8" bore if for 1/2-ton and 1-1/4" bore is 3/4-ton.
