Getting back to the distributor being grounded issue, what's holding the distributor in place? The only thing I see is the bracket (for lack of a better term) that the distributor slides through, which is connected to the vacuum advance. It's the bracket that you loosen, then tighten, when you're timing the engine. I guess ultimately the question is: how does the distributor get grounded properly (other than having to connect another grounding source, like a wire from it to, say, the engine block)? Thanks
