I've installed several different steering skids. The Kilby skid was fantastic and severed me well for many years, but it's no longer made. I've now installed the Savvy skid on three different aftermarket bumpers, it worked on them all and is my new favorite. Lightweight, strong, and fairly easy to install.
For the Savvy install, you'll likely need to drill two holes in the bumper, but that's not a big deal. Once you receive the skid, mock everything up and mark where you need to drill, using a center punch. Depending on the bumper, you may or may not be able to get the top nuts on with the bumper installed. Just be sure to check this when putting everything together.
The only real advice I can give it to liberally coat the single bolt that goes up into the steering box mount with anti-seize. Once you put the bolt and nut in the steering box mount, water will accumulate in there. The anti-seize will help make it easier to remove the bolt and nut, should you need to. To help with this, I drilled a small drain hole to allow water to escape.
The only other tip is you don't have much room to work with when dropping the nut in from the hole on top side of the steering box mount. I dropped the nut in and used a magnet to help position it, hand tightened the bolt to start it, then hit it with my electric impact.
