Go with the 3 piece.
You will need a 7mm wrench to get underneath the bumper cover to remove the bolts.
I went 3-peice
Although if you get a 2-peice grill, you can make the inner grill trim that is stock on your car work with a little modification. It's almost the same as the 3rd peice in the Mach 1 kit except that the slot isn't cut out where the pony gets mounted. A little trimming, and you would think you bought the 3-peice grill.
Here's my 3-peice grill. I'm a stickler for details so i wanted the real parts instead of modifying the inner peice and getting a 2-peice
