Getting ahead of myself before the kit arrives...

We've reverted back to the front bumper with integrated skid. I understand that the newer chassis (SCT410.3) are countersunk on the forward most set of 4x15mm screws. Is it intended to allow the bumper skid to simply cover the front screws, or, can one use the two mounting holes in the skid to help secure the bumper? Just clarifying. Perhaps it doesn't matter much. You could drop in a few o-rings to fill the countersunk void if you decided to use the skid mounting holes.
