I'm probably going to do mine this weekend. I'll post some pictures.
Here's what your dealing with underneath. That white paper is the template for the Baja Designs Squadron lights. If you just cut the square out from behind the plastic insert, you lose a lot of light. But if you cut much more, you'll lose the integrity of the plastic and the ability to attach it to the adjacent piece.
I might leave the shitty plastic pieces off. I'm gonna see what the bumper looks like without them. I might have a fab shop weld in some metal fittings and get rid of that horrible ill fitting plastic. It'll probably cost a lot, if you can even find someone willing to do it. It traps so much dirt and sand it's all stuck under the trim. It'll eventually wear through and start to rust. Very cheap bits on expensive bumpers.
