Specific used catalytic converter needed...

This may be a shot in the dark because this is a very specific part, and only because the truck is so old and doesn't have enough good metal left for welding, this is the only part that will work. Hoping for a used part if possible.

I need a direct fit 35" catalytic converter for a Mazda B4000, 1995.

No luck finding a used one. Any help would be much appreciated.
