So I spent all day putting the car back together. Throttle + linkage + carbs + fuel all done. I have some minor repair on the cooling system and I have to find a few hoses and washers and I'm good to go. Maybe next weekend?

One slight issue. I have 2 bolts that I have discovered I cannot reach. At all. They are 2 bolts that hold the carbs on the intake manifold. It's the back two below that throttle linkage. You have to put the carbs on after you mount the manifold...won't fit otherwise. And the linkage has to go in beforehand as well or you can't tighten it down. Maybe if I had some custom tools I could do it, but really, I'm just a little lost how to put get the nuts tight.
