Em, if it were mine I'd buy a new radiator and if necessary, replace the lines or cut back the old ones to a point that they can be re-flared, then extend them to the cooler in the radiator. It sounds like the PO had a leak in the radiator cooler or at the fittings, and elected to swap to external. Mounted to the front of the radiator it 1) reduces air flow through the radiator and 2) pre-heats the air going through the radiator. A supplemental tranny cooler (to cool more than the internal unit in the radiator), is generally mounted in a spot where it can get free air flow, but not in front of the radiator in my experience.
