You probably have got no response to this since so few S/SS cars actually run a cooler on their cars.
Most just run a loop on the cooler lines.
If you feel you must have a cooler , look at the ones Derale Performance.
Very strong and efficent ,with pipe thread bosses to use AN or JIC type fittings.
I have my cooler lines for the cars I build made by a shop that makes Hydraulic lines.
Crimped on ends and hose that is made for hot oil and extreme conditions.
The outlet temp from the converter to the cooler can approach 300 deg. ,regular braided hose is not up to the job for the long haul.
