Can you post a photo with the final result looking head on? Curious to see the red scoops showing through the grill.I used a Dremel tool with a new plastic cut off wheel.
Total time to cut, clean up the edges and bolt in is easy on two hours.
Could be less depending on how much you clean up the cuts and drilled holes.
I worked on that a while with files and box cutter. It holes drilled correctly then bolting is no issue. I also cleaned it up and rewrapped my red stripes. Use use tinted film so they match the tinted film on head lights. The older tint on grill was showing age.
