1969 chevy 4x4 1 ton PU

[frankbanks]

Wondering if someone here can help me with some info on a truck im thinking of buying.

as the title says its a 1969 chevy 4x4, I was told its a 1 ton, my question is this, would this have drum brakes for sure or is it possible it could have disks? it has a 6 cylinder 4 speed combo and i was wondering if anyone has any idea what gear ratio it would have being its a 6 cyl with 4 speed combo?
