Harris Cyclery in Newton, Massachusetts - USA, will do a spoke calculation for you. And then hope to send you the spokes - your call, of course. Just ask for the correct length. Include the exact model of the hubs - including how many holes. The rim. And the build-pattern (such as laced X3, 36H hub).
They are great folks and deserve our business. It's the haunt of Sheldon Brown.

I'm not sure on the dimensions, but that's a reasonable guess... but LX has been relaunched as a high-end trekking group. The new Dynamo looks pretty nice and is unavailable in the US. I'm thinking about buying the similar DH-3N80 (also unavailable in the US).
