Service to obtain the necessary part excellent. Fitting the part tricky.
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.
