Hard To Find Exhaust Pipes...

[Autolite]

It seems that the factory exhaust pipes for the Fox Fords are getting harder and harder to find. I need the intermediate exhaust pipe for my 1980 Ford Fairmont Sedan (Walker Part Number 44621). Does anyone know a good source for these older exhaust pieces? I am not wanting to go to a custom exhaust fabrication shop unless I absolutely have to. Many thanks...
