trans cooler location?

i recently purchased a 29 ford roadster. [350 chevy,350 turbo]
the car has no trans cooler on it. theres a trans
line, about 6 " long, coming out of the one opening, and curled in a spiral, the going to the other opening. i want to install a regular type of a trans cooler on the car, but where do i mount it? theres no room at the radiator area. so my only option is under the car. but where? does anyone know where these fiberglass built hot rods put theirs? what are my options? thanks for any help.

Or mount a "small" radiator like unit (B&M makes a nice polished aluminum one that's available through Summit for example) near the trans, trying to avoid being too close to the exhaust. Usually mounted parallel to the frame rail, a simple aluminum sheet stock "scoop" can be formed to direct "cool" air from underneath.
