Physical size of Tranny Cooler?

[Skibug]

I was wondering what the biggest physical size tranny cooler I could put in front of the Radiator? I have a 96 sport 4x4 with the 4.0. I was looking at putting one that has a size of 15.5" x 10" and it looks kinda tight and covers a good portion of the bottom of the radiator etc...

So basically what is the biggest physical size cooler that can be safely put there?

This is just an educated guess, you probabally don't want to block any more than a third of the air flow to the condenser and cooling system
