The core measures 45.625" high by 38.625" wide, 2" deep. It has a 2.5" inlet at the right and a 2.5" outlet at the left. The unit carries an oil cooler at the bottom and no filler neck.
It replaces 44 OEM and aftermarket numbers, among them FRE51, 0526621001, 0526621003. 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.
