I live in Provence, South of France and therefore must have presented a little more of a challenge to Ken getting stuff to me. I bought two hooks, two clevis rings and two lengths of chain at the beginning of this year and I can't speak too highly of a) the help and advice he gave me in phone calls and b) the quality of the stuff. Oh, and it arrived perfectly packed and with a little present or two as well - to take up some of the weight allowance in the boxes - which was very kind of him. I bought the chain because I couldn't source chain down here with the same rating.
I installed the hooks on my Kioti without any bother except that I was glad I had kept the spanners and sockets from my teens in the 1960s when in the UK we were still non metric. You chaps in the USA are lagging a bit behind you know!

I must admit my mind is still a mix of inches, feet, yards and metric though. And then there are miles, kilometres and nautical miles. Not to mention litres, imperial gallons and US gallons. Some of this stuff from my flying days when Cessna and Piper aircraft could have a confusing mixture, some adjusted for the UK and some not.
although I've done someheavier work with the hooks and chains, here's a photo of my Kioti taking away part of an old Mulberry tree.
