The "forward jib assembly" I was referring to was the bridle foil. I was confused because some of the pictures I had seen of the 5.7's had them but they must have been a user modification. This boat comes with the stays, forestay and bridle for rigging as well as the blocks and sheets for the main and traveler. Anything remotely having to do with the Jib is gone.
Any help in trying to get this boat going would be great since it is in amazing condition otherwise.
