Replacing the plastic sheaves at the ends of the track of the stock Rutgerson track on the H.28.5 is both easy and cheap. I bought some sheaves of the right diameter from BoatUS and just pulled the screws out and dropped them in. If you really need to replace the whole track, take a look at the archives of the Hunter 28.5 group on Yahoo as a number of H28.5 have done this. See link.
