Stop in for a cup of coffee

So question men. If you wanted to install a aftermarket trans cooler, where would you locate it? And don't say in front of the radiator....that is obvious....Best idea to get heat away from trans and engine.....I know options are very limited....
If it were me, I’d mount a thin, but long one, directly behind the front bumper/valence.

I’ve also see some mounted in the rear valence, there’s surprisingly a lot of air flow under the car on these old cars, especially in that area.
