I just inserted them thru the front. When I was snipping the plastic I did just alittle at a time so I would have enough of the bars to wedge between bumper and lens. i ended up just leaveing a couple of them just alittle long so they could have more to bite , if that makes any since. I drove it and one of the two is alittle loose, so Im going to take them back out (easy) and put a couple of little pieces of 3M tape on a couple of key areas to hold them down alittle better. See ya Nascar, By the way, your rig looks GREAT
