Looks great.
Depending on what lights you mount you'll probably need the hole diameter larger than what you show lined up on the body. I can only speak towards the trucklite version that EVO supplies. Measure the rubber grommet
or hold it up to the body and use that as the guide because it will have to get shoved in along with the light. If you only cut it large enough for the hole dia in the skin you'll end up having to pull the damn things off to enlarge them
after you find everything won't stuff in there.
Another good idea while you're at this stage (and using the lights above) is to take the time to mount those little resistors somehow or tie them up so they do not hang from the wires. They get very hot and may eventually pull loose
over time and become disconnected. Mine did and I ended up installing larger resistors on mounts I made up. You'll know this happened if you get a fast blink from the turn signal on down the road.
