Just an update to this thread, I purchased the 3M Dual Lock per my previous post and installed the front plate with it, using a piece in each corner and a piece in the center of the plate. It works great!

Can't believe more people don't use this method. The tape sticks to the metal of the plate and the paint of the crossfire much better than expected! For those who are concerned about the sturdiness of it, I have already driven upwards of 60-70 mph the plate stays firmly put. My only concern is that if and when I go to remove it, it might take some paint with it (have no way of knowing until the time comes). That being said, I'll take a little touch up of the paint over permanently drilled holes in the bumper any day!

Oh yeah, did I mention 8 pieces of this tape on eBay is $6?
