Is anyone aware of how to install the Spare Tire kit or where I might find dealer installation instructions? The kit itself is kinda pricey, $369, and I was looking to do it myself to avoid dealer installation costs. I read something some where online the drilling might be required for the center bolt that holds the tire in place. The rest should be a "No-Brainer" just swapping out the current foam insert with the new and fitting all the components in the cutouts.
