Does Hobie still make replacement cams for the old style castings ?
No, unfortunately not; they are a discontinued part on a discontinued boat. They were discontinued in 1989 for the newer design with plastic cams. I don't believe they ever sold the cams separately anyways, instead selling the complete assembled lower casting. They didn't typically wear out or break; the more common problem with the old style castings was that they were a little thin, and some of them (the castings themselves) broke when the rudders failed to kick up, or even from excessive rudder loading from a crashing wave or the like.
If you have a problem with yours, your best bet is to find a used lower casting on ebay (they're around, and typically go for ~$65 each, but not terribly common because of the aforementioned breakage issue). The only other options would be to have somebody make the part for you, using the other one as a template, or buying the newer style lower rudder casting and mating upper casting ($500 upgrade new). Note that if you change the castings, you'll also need to replace the rudder gudgeons with the newer style to fit the newer casting, including drilling new holes in the transom and filling in the old ones.
