What Master Cylinder for 1956 6400 truck

I have a 1956 Chevy 6400 dump truck that's a 3/4 ton, which Master Cylinder do I require?

I have the large 6 cylinder inline.

Thanks,

It may be a 1.5-2 ton, I'm not sure.

Does anyone on here know how to remove this Master Cylinder Plug - it looks like a square shaped plug about 11/16" ? Is there a special tool wrench to remove this?

To answer my own question, I used a 22mm socket 12 point and it fit perfect. Opened it up and master cylinder was bone dry after letting her sit for 13 months.
