Found the same post and the end result is he pulled one cog off his cassette and made it a 7 speed. Not really what I'm after tbh. Cheers though.
(I did read the other bits as well, but it seems far more complicated to be stripping the freehub apart, checking fitting etc and then trying to find a compatible replacement to 8spd. A bit beyond what I'd want to do tbh, though I'll keep it in mind if I can't get hold of a wheel already running 8spd)
