Welcome to the site! great advice for you in this thread! I completely agree with getting it running. I have a 58 2-ton I drive daily, I re-did the interior but left the outside of the cab original for now. As Stotman said, brakes, engine, then trans, change all the fluids and get lights and gauges working, putter around with it and then drive it a bit (unless you have it too far torn apart).
Also, come see some others close to you that may be a bit farther along to get you motivated!
Not sure where in Washington you are but if close, come by and see me and talk trucks!
