If you mean trans and t-case skidplates, I think both IPOR and Tojo Products are making skidplates. And while I have never seen them advertised anywhere, while I was in PA last fall for the BBRC Fall Crawl, I saw a skidplate being offered by David Crum, but I don't even know what he calls his. It 'might' be CWC.
I Was going to suggest the same thing as Roberto. I found a couple of guys in my town that do phenominal welding. The guy who made my bumper is a perfectionist with his welds. Check around for some local 4x4 shops. This way you get exactly what you want.
