E89 Z4 quality diamond pattern grilles

[First Timer 22]

Hi,

I've ordered three sets of diamond pattern grilles for my E89 (i like the look) but none of them fit properly (clips too short on sides and bottom along with not allowing for the stock nubs that hold the grilles on the bottom).  I don't want to modify my bumper to get them to fit. 

Does anyone know of any high quality ones that install like the ease of the stock grilles? 

after all the trial fitments I've become somewhat of an expert on how to replace the grilles without any damage, lol.  Also I've noticed that all the adverts for the diamond grilles don't actually show them installed on the E89.

any and all help appreciated.
