Those grills come as OE part for the B14 2000 Sentra Limited Edition, and not for the 200sx known in Mexico as Lucino.
That Sentra is very popular here in Mexico, so aftermarket grills of less quality are being sold here in Mexico and in the US at eBay.
I've had the chance to check all the aftermarket grills even the OEM grills, to compare them with the ones I'm selling at eBay, and the results are that Nis-Knacks sells Nissan OEM grills, at ebay you find Brand less grills, and the ones I'm selling are the same as OEM grills exept for the Nissan logo in the back, they are made by the same manufacturer, the only difference is that these ones don't have the Nissan logo in the back.
