Need SD45 main PCB

This is something I've been trying to locate for weeks now. I need a main PCB for an SD45 I'm rebuilding. I've called Navin with no luck. Lewis said he'd try to look into it. I think I could use a main board from a Dash 9 or GP40 but as of now no one seems to have any. I would buy a used unit that is damaged or dead just to part it out.I know it's kind of bold to ask but does anyone have or know of any available any where.
Warmest Regards,
Bob V.
