1997 Ford Ranger (Heater Blower casing.)

I have a 1997 Ford Ranger which has been wrecked on the passenger side front and pushed the AC and Blower over some, the black casing that was around the heater blower is broke, I need to get one but I dont know what there called, and I cant find any without the name. Does someone know what there called? Thank You

It's called a heater core casing. But why replace it? Since it is a 97 just get some duct tape and tape it together so the pieces fit. They are a PITA to replace. Tape it up and paint it black. Job done $$$$ saved.
