TPR0010 is a downflow radiator for the Peterbilt 379, 357, model years 2003 to 2006.
The core measures 36.125" high by 26.0625" wide, 2" deep. It has a 2.5" inlet at the center and a 2.5" outlet at the left. There is no integral oil cooler and no filler neck.
It replaces 17 OEM and aftermarket numbers, among them 770008, 770008ST, 7708. 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.
