There is a Ronstan RF 879 double cheek block on port side of the deck of my IP420 that leads furling line and main halyard from mast area to the cockpit winches. Well, this block failed and I cannot find a replacement one. The ones installed by IP factory have slightly curved base and the deck post on which it sits is molded to that shape. I can find a flat base block but nobody even knows about the curved version of it. Any ideas where and how to find one?
after unsuccessful search I gave up and in desperation bought a regular, flat bottom block with an intention to sand the post to flat. And a surprise - of course I tried to mount it first, the base is stainless, but so soft that if conforms to the shape of the post when I tightened the screws!
