Actually, both of the pickups in the links below are supposedly designed for use in a stock pan, and both appear to have the "shoe" on the bottom.
The only difference I see is that the tubes have a single bend instead of three. Assuming there are no fit issues, this should be a superior design since the oil would travel a less circuitous route into the pump.
Maybe I'm just overthinking this, just like every other aspect of this build.
