Yup, the high and low resolution sensor are on a machined plate with a machined billet cover. Kind of looks like those covered plates they have when you eat in a hospital room.

For spark, I use a system similar to the LTCC. I threaded 8 holes in my valve covers and attached the coils there. I think it looks trick.

I agree that if you were so inclined, you could probably fit both sensors in a distributor. One of the problems is, you'd have to have a "normal" cam ground so that it had the dissy gear, and the LT1 nose. There would be some slack in the system, but you could probably tweak it out with a little tuning. And spark, that's another thing.. you would need to decide how to get spark to the cylinders. If you went the LTCC route, your holes on top of the dissy would be pretty much useless, and the cap just a cover. It would work, but it would look bad, and would have to be moisture sealed.
