Thanks again guys. I found the problem: The outer ring was the wrong way round, EVEN though the stamped lettering was facing the way the instructions said (outwards)... By examining the ring it was obvious. It is now correct: the indentations for the bashguard are on the outside, the ugly end of the rivets on the inside, the spacing is perfect, and to top it all off I googled pictures and enlarged them until I could compare all the details.... BUT the stamped lettering is on the inside...
