That link was just to your cart... This is the cover, looks nice btw.
I saw STL's rear diff cover and thought it was pretty sweet. Its a 2002+ Explorer IRS cover w/ the suspension mounts cut off. I looked for about a month on eBay and ended up finding one for about $20 (under $30 after shipping.) Took a cutoff wheel & a sawzal to get the mounts off. Cleaned it up w/ a flap wheel & sprayed some clear on it. You have to get longer bolts, 'cause it's thicker..... I'll look for a pic.
