Possible project truck trade?

[TwoFiftyShifter]

Saw an ad on CL for a 1954 3/4 ton 3600 dually, 216 I6 4-speed. Runs and drives needs lines and master cylinder to stop. It look neat, dark green and not insanely rusty from the pic for up here. I emailed the guy (why not leave a phone #?) and asked him if he'd be intersted in a trade for my truck. '64 GMC 1/2 ton short bed pickup, 230 I6 3speed, runs drives and stops, some rust in the cab.... What do you guys think? My 64 isnt on the road I was planning on doing stuff to it this winter, but its been sitting for 4 months, I wouldnt mind and older project to tinker on..... what do you guys think? Is there a such thing as a dually 3/4 ton? Flatbed truck.... shouldnt it be a 1-ton? Would this have a 2-speed rear? Let me know what you think.
