1972 International Harvester 250 C need a part number

Hello,

We have a 1972 IH 250 C Track Loader with a rusted out manifold.

This part bolts to the bellhousing and exits exhaust from the turbo. It curls around and bends to connect to the exhaust stack.

I was hoping someone might know a parts source for this....

-Or maybe a part number for this to assist in a search if you had the manual for this machine.

Thanks, - Joe123
