Wow I just looked at the pictures. You've got a prize there. I dig the hippie windows. I bet some hippie has had somebody's daughter in the back of that truck.
Those side turnsignal lights are rare. Don't let anyone talk you out of them.
If you try Bowtie70ss's idea and "disconnect the coil wire and rock the truck back and forth by hand." I'd recommend trying it in second or third gear.
Good luck with your project and have fun. That's what it's all about. If you get discouraged, as we all do, walk away from it a few days then come back fresh.
