Trans cooler mounting??

One of my next projects on the cuda will be to install a B&M plate type trans cooler.

Are there any recommendations as to the orientation of the inlet/outlet?
Does it matter whether they point downward or sideways?

Not a big fan of the "zip tie" type mounting through the radiator, planning to mount on some type of rigid bracket behind the grill but away from the rad.

Anyone with a similar set up I would be interested in photo's if possible.

Thanks Roger
