TMD0012 is an A/C condenser for Mack trucks.
The core measures 33.75" high by 10.5" wide, 1.375" deep. It has a 0" inlet and a 0" outlet. There is no integral oil cooler and no filler neck.
It replaces 42 OEM and aftermarket numbers, among them CON0071, 041209, 41209. Searching any one of them will find this part.
On condensers the line fittings and the mounting bracket positions decide fitment. Core dimensions alone are not enough to confirm a match.
