It's actually quite easy man - for the bottom, I took the stock grill and cut out the black plastic mesh (keeping the frame). Then I took a piece of APC universal aluminum grill, cut and bent it to fit in the frame, then just used some thin wire to hold it in place. For the top, I took out the stock grill, made a patern with some paper, and then cut out the mesh to fit. I made the top of the grill to fit where the screws go in the bumper by the headlights. The bottom of the grill is just wired to the three little plastic nubs in the bumper. Its hard to explain - I'll try and get a pic that will help.
