When I swapped the aluminum ranger pan to my t bird engine, I had to put the ranger oil pump on because the body of the T bird pump was too wide to fit in the oil pan, the pickups were in the same location if I remember right though.
There's another complication or two in putting the aluminum pan on the T bird engine though, the oil pan gasket configuration is completely different, in '86 they changed from a two piece gasket to a one piece gasket placed in the oil pan, the issue is there is a "trough" in the rear main cap, my solution was to fill it with JB weld, which seems to work fine. The other issue is a few bolts are larger on the T bird block than the Ranger block for the oil pan, I just drilled the pan and got some 8mm bolts the right length to account for it, it's just the bolts by the rear main if I remember right.
