AZ WTB - 68 to 72 GMC or Chevy C10/20 Truck

[IT Cowboy]

I am looking for a truck that is mostly original and a survivor or has at one time been restored. My biggest requirement is that it is rust free or mostly rust free and would require little mitigation. It must run well, have no fluid leaks, be reliable. AC and auto trans. would be preferable but not required.

I am in the 20 -28k range and I am willing to go about anywhere is the US for it and would most likely fly in and drive it home to Arizona.

Thank you for looking
