Just an update on this. Well, without explanation, I get a refund into my bank account for the blade set. This was after I sent the supplier an email re the issue. I then questioned why they simply refunded without reason, and they said, oh, those blades are made wrong, they are 1mm too long. Would have been nice to know this before my mate went to the trouble of fitting them. Looks like they were just going to let it ''through to the keeper'' and wait until we come up with the problem. As soon as we queried the blades with the supplier, they refunded, so they knew there would be a problem in the first place. One supplier in my little black book.
