Looking to buy ECM

[888thenumberofthebus]

My ECM in my 1996 international **** the bed . I sent it to be fixed and they say the main chip is ruined and can’t be reused . So I need to buy a new one but it’s proving very difficult. If anyone has one or knows someone or a company that sells old ecms I would greatly appreciate any help
The ECM part number is
1807389C1 or 2596953C91
The engine is a T444E
