We purchased the med-range Harken windward sheeting "kit", I don't recall the part number. The "kit" (I think that is what they call it) includes everything but the new traveller car. The kit holes are about 1/16 off the alignment of the original equipment car, but a minor adjustment to the holes (with a tungsten-tipped drill), and it was a bolt-on item. We removend the cleats the pulleys from the old arrangement, and mounted the pulleys on the end of the existing track to give 4-1 purchase. We ahve raced the boat constantly (~50 races/yr) and the travellet hads worked flawlessly, provide it is well lubricated. One of the best upgrades we made.
