Hi Pat,
What you need is the piece which fits between the end of the push rod attached to the spinner in the middle of your wheel, and the brake mechanism. This I understand is called a "Brake Slug," and is nothing to do with one of those slimy little critters that some birds enjoy eating. I contacted a Lewmar agent for one that I needed for my B36(2002), but the length of the slug he suggested I needed did not match up with measurements I'd taken, so I declined their offer and made one up from a piece of 8mm stainless rod that I had. First I checked the length of the hole inside the steering spindle and then deducted the length of the push rod attached to the spinner to determine how long the slug needed to be. If you intend to make one up for it yourself, it's worthwhile making it significantly longer so that you can shorten it later for any error in measurement. It's important to ensure that the slug you make is a reasonably sloppy fit into the spindle as you don't want it to get jammed in place, also don't put any grease on it until you are sure it is the right length. Once the slug is inside the spindle you will need to be able to retrieve it until you are sure of the right length. To retrieve it I used an 8mm disc cut from some double sided sticky tape which I stuck to the end of the push rod. I then screwed the spinner up until it was in contact with the new slug, and when unscrewed the slug came out attached to the end of the push rod (that's why it needs to be a sloppy fit and free from grease !!).
My boat has been ashore since I made and fitted the slug, so while it seems to work a treat, it won't be until after launching in April before I can check that it is exactly right. It does however appear to be just the same shape as the one that Lewmar offered, except it is the right size unless of course there was something else missing from within the steering assembly.
