Rooster provide the necessary part very speedily. Excellent service.

However the actual part came with no instructions on how to fit it. I had to go to a web site in America to get a video of how it went together. I am pretty handy but you needed drills and heat guns and luckily I had a vice to hold everything together. It took me at least an hour to fit.

I only replaced this part as the old extension tiller universal joint was showing signs of wear and I had to use this replacement part to fit with the tiller extension which was Ronstan.
