I have a few parts taken off an '87 T-dub. http://www.jrvintagecycles.com/Yamaha_TW200.html
Mine has so many weld bumps on it from closing up constantly occuring new rot-out holes that it looks like hell now. I don't need the back (muffler) section.
I've got the header from my 1994 in good shape. PM me if you're interested.
