Factory UTV skid install question

I am installing a 1/2" skid kit and have a question for those that have installed one.
The rear most skid directly contacts a domed area under the driveshaft. Did your skid have that area relieved/cut out or did you just tighten it down and let the plastic kind of form around it? The kit I am installing has no relief and just presses against the high point of that dome. Seems kind of odd that it would be pressed up against that.
