I have the Slee transfer case skid and you can see pictures on Christo's site.
I also have cat skids welded to the custom sliders and have posted pics several times. You can search the archives here and the SOR archives for the pics. Let me know if you cannot find them and I'll poke around and see what I can find.
Junk posted pics of his sliders with the cat protection so that's another that you can search for. I'm sure that pic was in the SOR archives.
C-Dan and Rogue have both posted pics of their cat skids (Hanna's) Check both archives.
Bill (photoman) recently posted pics of his new front skid plate. It wasn't installed but there were several pictures of the construction. Great pics!
