Thanks for all your replies and yes my ohlins damper is fitted
First thing is Jasper now has my original yoke so I can't compare it. To fit this new yoke I have to offer it up - it won't go straight on so I have to hold the front brake and push the forks down and push on the yoke so it fits on the centre nut. Any other way and the centre nut don't line up with the middle yoke hole.
