Campag 8 speed has a different spline pattern to the later 9/10 speed. Did you take this into account when ordering your Gusset sprocket?
As far as I can tell there's no option for diff campag patterns with the gusset stuff, and I have to say I didn't know patterns changed for 9/10 speed to be honest.
