The core measures 51.625" high by 25.875" wide, 2.25" deep. It has a 2.5" inlet at the left and a 2.5" outlet at the right. The unit carries an oil cooler at the bottom and no filler neck.
It replaces 9 OEM and aftermarket numbers, among them NAV35, 2596325C91, 3E0117240000. 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.
