Hi Jezza,
Remember to take into consideration the cost of a spray/colour coding them too, as they come in plastic/primed and won't look great. I got a single piece plastic type which is fine, fitment is okay but feels a little flimsy compared to the 2-part metal plastic genuine one. You can get a 2-piece de-badged grill which I think would be more sturdy.
Although I could argue that I'm saving weight with my plastic debadged 2-slat jobbie.
