I used a TheMightyHobie18 roller furling and had to change the bridle wires and the upper forestay which had to be a tad shorter. To this last one you must insert the swivel. I did this myself using West marine equipment and leftover wire from a stay. I can tell you taht next time I'll have it done professionally. Getting the wire to bend in the thimbles was a pain. I like the new system as I couldnt stand the noise of the jib flapping when reigging/derigging the boat. Let me know if you need any additional info.
