Just did this today, Looks pretty good. Follow those directions pretty closely but i would modify it just barely. Put screws only in the corners of the grill. Do it in black. If you do it make sure u keep the mesh tight. Good Luck!
this is a very good guide on how to make your own, i dont like the fact that you can see the old grill behind it though :\ i dont mind buying an already made grill that looks like black mesh but i cant find any at all except one that looks like poo. If anybody has any links on good black mesh grills that i can buy please let me know. thanks so much again for that link
