2003 cab lower front grill

Does anyone know if the lower front grill (the one below the number plate) is a different height to other models? I bought a replacement one from eBay (genuine one, 2nd hand) to replace mine that got damaged and the one I bought is about 30mm to short??

I assumed all front lower grills would be the same size???

Can anyone shed any light please?

Cant answer specifically about the grille, but pretty much everything on a b6 cabriolet front end is specific to the cabby and totally different to the saloon or estate car variants.
