Pulley-mounted crank trigger w/stock Magnum EFI - trigger notches?

That sensor mount that hipotec sells is probably the easy button here. If you’re using a 727/904 you’ll have to notch the bellhousing but that’s easy. And just use a stock magnum flexplate. I believe all of them are neutral balance as the balance was in the converter.

I've never been one to buck the easy button if it gets me where I need to go with the least amount of fuss - provided it's not outright hackery. I like the simplicity of that bracket, and it doesn't look overly fussy.

Notching the bellhousing is easy, but my car is an ex-318 with its original 904 at the back. As such, my converter is still neutrally balanced; I used a B&M flexplate to get the roller LA360 to play nice. It's going to take another converter or I'll have to weld on some weights to the existing one.
