Ed,
The tapped holes are already in the Ford Racing cover for an
oil cooler. There's one at the very bottom that goes to the pump inlet, and another near the top on the passenger side for the return.
There's a boss at the lower passenger side that I drilled and tapped (1/8" pipe IIRC) for a temp sensor. They must have been having an Hispanic humorous moment, because it's labeled "SENOR," apparently intending to label it "SENSOR."
In addition there are bearing cap preload bolts for the differential bearing caps.
There's a PDF of the Ford installation instructions here:

It mentions the
oil cooler port locations and the torque specs.
Here's the Ford link:

Just another option; not saying it is the only game in town.
