Have you considered relocating the oil cooler? Many of the skid plates require relocation of the oil cooler to a vertical position at the side. I haven't done that to mine, but know it's a possibility. Touratech sells a relocation kit. Here's a link to the kit on their website.

Here's a pic of a modified oil cooler that's been relocated as I described.
