Tvr wedge fhc trim part

[mike various]

Good morning I'm after some help if possible. I'm trying to help an owner out in the US who needs some parts.
He's after the trim which goes on the b post on the outside.

I have a driver's side one but not the passenger side side.
He's tried appealing on the face ache sites but no one seems to have one. Can anyone help?
Or does anyone know someone who could make one from fibreglass if it sent them the one off my own car to be used as a pattern?

Thx

Mike
