The vertical part on the grille

[Pentoman]

I sold my 2006 Vantage to a buddy but we noticed that one of the vertical uprights on the grille was missing. Horizontal slats are all there, just one of the vertical plastic uprights that hold them in place.

It's just a small piece of plastic - does anyone know a source for these? Or have a spare/damaged grille that could kindly allow me to buy one? Two people would be extremely grateful not to have to buy a new grille at £600+.
