Also, I think that if you are using the DR350 wheel as your dirt wheel and always run a knobby on it the cush drive wont be needed, the knobs will buffer the trans on road. My DR350 is a plated dirt model with no cush and it seems fine on the street but it doesn't spend much time there. It has the same forks as the RMX as well, as it is a '98. They are great forks and are fully adjustable, they seem like a no brainer mod to me as they fit the stock DR650 triple.
Thats fine if it just needs spacers. I have a lathe to make spacers. I don't care about the cush hub like you said it will only be for my dirt/ ice tires. I might just get a complete bike for the front end and see If I can make the rear wheel work too.
