It replaces 59 OEM and aftermarket numbers, among them FRE31, 91653, 91661. 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.
