222
I don't know how it compares to the 222, but mine was actually a fairly simple process. Do you have access to the swing keel? Also, I don't know what kind of weight you have in your swing keel/board, but you'll need to take that in consideration. For mine, I supported the board then removed the 6 screws from the 2 plates (2 large and 1 small from each). After the plates, I removed the wedges that hold the pin up. It took some wiggling to get the pin to drop down because of some type of caulk that was used to hold the wedges up. Everything dropped down after that. Here's a post I had about it. Some others posted some good pictures of the parts. Again, it's all for a 222 so don't know if this is any help or not.http://archives.sailboatowners.com/pviewarch.htm?fno=60&sku=2008070082622.63&id=529023&ptl=#2008074200131.64
