Rick's post reminded me of something; you can put the dizzy in any way you want by just re-assigning which post is #1. The order doesn't change, just the starting point. Doesn't matter if you have vacuum advance or not.
Think of it this way. The body of the dizzy will only fit in certain ways. It is limited by obstructions, the vacuum can, access to the cap clips, and so on. The cap is keyed to the body, and only fits one way. But the dizzy shaft, rotor, reluctor (or points cam) can fit in many ways. I don't remember how many teeth are on the gear, but it will go in that many ways. I don't know if this will really help with looming the wires. I would think it would cross just as many as it would un-cross, but maybe so. I'd have to play with it and see.
Also, don't get carried away with looming the wires really snug; you can make the cap really difficult to get off.
