I've got one from my STS-1000 DS but its got a crack on the non drive side bottom shock mount. I'll take some pictures when I get home. I was told a few years ago that the crack was small enough to get fixed but I never did.
Well the polished aluminum made a pic harder than I thought and my cell phone is not going to cut it. Here are a couple showing the entire thing and where the crack is. I'll work on a better detail pic to show the actual crack itself.
