In the upper left corner you'll an entlarged view of it.
However I really do advice the Riley (Yacht Fittings) version of this universal joint. The rubber joint is the same but is cleating mechanism is just way better. Sadly Riley doesn't sell direct to private persons. But I do know a few agents that have them.
www.catamaranparts.nl sell thems for example. I got mine through a certain mutual Australian friend.
