thanks for the help everybody, i have re-tapped the threads earlier on and the bolts now go in very nicely :)
the only problem is the cassette, it does work, but i want to get the metal filings out, i know they are in there because it has skipped a couple of times recently.
it does run but i dont funny trust it, ive wacked it in the bike now and it seems fine to be honest should last me through my trip to france :P, but if a tooth snaps off, then im f**ked because there will be no way to access the bugger!
if that happens i'll give profile a call,
cheers people :(
Will
