Here's the one that Bowsher referenced in his email. If you're not into fabbing something yourself, it's your best bet if you can stomach the price.
A little story on the development of this item. Years ago, I was on a run with some friends, including a friend that had recently swapped an Explorer engine into his truck (this was before they were common for swaps). We were parked along a trail which happened to be dusty and my friend's truck was idling. I noticed a lot of dirt/dust swirling around underneath his engine which told me that his fan was sucking drawing a lot of air from places other than through the radiator.
A short time later I did the Explorer swap on my truck and since my buddy Doug Schulz was the general manager at Ron Davis Radiators at the time and I was switching to their radiator, I inquired whether they might like to develop an Explorer swap shroud as a product for their portfolio (since I wanted one!). Doug agreed and they developed one, using my truck as a guinea pig.
A few years later I swapped in an Atlas and my 700R4 and needed a body lift (and a body lift fan shroud) - Doug was still working there at the time so they again used my truck as a guinea pig to develop the 2" BL version.
I've had to modify the mounting holes a few times as I've switched radiators as least twice since then, but it's still sitting in my truck out in the driveway right now.
