What about using parts from another manufacturer?
Anybody else make CW?
Atlas made a dash 8-40 ... dunno if made in a wide.
Maybe Shapeways?
Maybe a skin graft.
Looks like your best option is a donor from an auction site or possibly a train show.
@TJ suggestion for n scale yard scale...is a good option, I have purchased many times from them.
Good luck
