Thanks for the help guys, I have an old 9 speed HG axle that I could just rob the cone nuts off hopefully, I will buy a new 7 speed freehub then and lash it on the 600 body.
edit;
looking back over those posts again it seems i might still run into difficulty with cones compatibility. I'll give it a go anyway.
