1960 C10 Won't Start! Help Please :(

[pudula]

Truck - 350ci motor, HEI, 700r4, 1960 Chassis
Story - started right up and pulled it out of the garage, washed it up. Go to start the truck to go cruise and she's dead as a door nail. First click of the key turns on stereo just fine, lights are all good, etc. Turn to start it and it wont even crank or anything.
Tests - starter tested ok, battery tested ok and has 12.5 volts. Bought and installed new ignition switch, nothing changed. Tried jumping it, nothing. All connections checked, battery terminals cleaned, etc.

Any ideas? I'm stumped.
