lost mine after a strip down and house move anybody got a set for sale(i will even through the wife in if i can find a seller).......
so that's why you've been away and no, sorry don't have any - saw a pair for £15 posted recently and nearly bought them for spares. Biggest damage problem apart from the obvious serious corrosion is people (should say muppets really) overtightening them as they don't know when to stop, particularly if they are stupid enough to use a torque wrench..
