WKs and carrying over sized spare tires

Joel's comment and suggestion touches on one of the two most common questions we are asked: I am going with over sized tires and where can I carry my now larger spare? (the other question is how does the Superlift 4 inch ride and handle?) First let me say that moving the spare inside is probably unworkable due to tire size exceeding the available space, moving it on the roof is not IMO aesthetically pleasing and potentially increases center of gravity issues, and building a (heavy) rear swing away is not financially in our best interests due to the costs involved and relatively small market.

When I contemplated trading my 2-inch lift for what was then a "soon to be available" 4-inch kit my biggest concern was indeed carrying a much larger spare tire. I never wheeled without a good spare that matched the set on the ground. The Superlift instructions--at least my old version--says "the factory spare tire/wheel can be used in emergency situations." I questioned this statement on principal and concern for my rig's driveline, but soon thereafter had a chance opportunity to meet a Jeep engineer involved in designing the WK/XK platform. This gentleman confirmed Superlift's statement--"just don't drive at high speed for miles down some freeway!" For me that was enough and the rest is history. I now run 305 series tires and carry a 265 series spare, which is deflated so it will fit in the OEM location. (And when the fellow doing my oil changes brings this condition to my attention I enjoy telling him "leave it flat--it keeps the weight down and improves gas mileage.") Anyway my point is I feel this "solution" is preferable to the alternatives. Besides I have never had a tire failure using the Goodrich or Goodyear 3-ply sidewall tires (though I recognize it is certainly possible and thus have tapped my wooden desk top a few times.)

Sorry about the response, but is there anything else that you would like us to work on, Joel?

I believe it was noted on a forum that the differential guards Superlift has posted on their website no longer exists to the market. I would also like to know about any ideas for taking up the slack. Besides the OEM diff guard, is there a possibility of coming up with your own line of diff guards. These could be economically sound and I wouldn't think they would take much engineering to fabricate. It could be a simple design primarily for protection and ground clearance.
