So, anyway, an adapter plate to bolt a DSM cam angle sensor to a cambox-mounted points distributor might look something like this:

Not sure yet how thick it will need to be, but I'm reasonably sure i can cut it out on the abrasive waterjet table I have access to.

It appears that a serpentine crank pulley from a Nissan SR18 or SR20 may bolt directly to the Fiat twin cam crank. The OE nissan part would include an elastomer for balance, and there are aftermarket pulleys with double elastomer or fluid-filled designs. as well as billet parts of course.

I'd rather convert all of the accessories to serpentine than tack on a serpentine belt for just the supercharger. Buying pulleys that are a bit shallow and shimming them out should be relatively easy.
