The core measures 31" high by 26.3125" wide, 1.4375" deep. It has a 2.5" inlet at the center and a 2.5" outlet at the left. The unit carries an oil cooler at the bottom and no filler neck.
It replaces 85 OEM and aftermarket numbers, among them INT60, 1A19009D, 20063505A. Searching any one of them will find this part.
On radiators the inlet and outlet positions, and whether the unit carries an oil cooler, decide interchangeability more often than core size does. Two radiators with identical cores are frequently not interchangeable.
