Hello-
I think ("think") this is what Shad is trying to convey.
here's a pic of "one" of my oil coolers - I have another mounted an the opposite side of the trans -both with thermostatically controlled fans.

No, that's still horizontal. My setup is vertical, and approximately fits into a transverse-vertical (i.e. perpendicular to longitudinal) plane of the car.
I don't have a good picture... Maybe I should get one of my dirty car... :-)
BTW, haven't talked to ya in awhile, Dan. How are ya?
Take care,
