Danno,
I used a used Hobie 18 furler and had a new shroud and pigtail made. You'll also need an upper swivel. The jib is tied permanetely to the forestay. If you are a recreational sailor, like me, once you have a boat with a furling jib, you will hate to sail a boat without one. It's great to launch, take a break, depower, etc.
Check some photos that I have on my webpage:
