Regarding the Lauterwasser handlebars, you may want to look at the Nitto/Rivendell Albastache, or one of the many dirt drop-type drop bars that are out there. You might find these much more practical. Plus, installing drop bars on a mountain bike can pose height/reach issues. I suggest you read the MTB drop bar conversion thread in this subforum before you get too far in your build. As someone has already mentioned, the frame may be designed for 130mm spacing. Lots of times you can fit a 135mm axle with a 9-speed freehub, but I know that on my 1986 Kuwahara, the chain would bind up against the dropout when I used a 9-speed cassette, so I am happily using a 7-speed cassette with zero problems. I also recommend going with a triple up front, and using cantilever brakes. You'll find lots of love for cantis on this board.
