>>Will this set of skids include a rear diff cover?

I hadnt planned on it, but if enough people want it, I'll make one.

>>Will pieces be compatible with other skid plates; I.E. Skid Row Plates

Good question. Our bumper skid works fine with the SR plates. I think you have to buy their front and mid plate together, so the only area of concern would be the rear plate and the gas tank one. I doubt the gas tank would be an issue, I'll see if I can find some pics of their rear plate, but we may have to wait until someone tries it to know for sure.
