We use the original cleat, cleat location, and single sheaves in each of the gooseneck and boom end castings. We substitute blocks and create a simple cascade purchase inside the boom in place of the two original single blocks to create more purchase.

The photo above shows the layout of the blocks to illustrate how the system works, but all of these components are installed inside the boom. The forward block is shackled around the bushing in the forward internal reefing sheave box with a longer D shackle which is provided with the kit. Another special wide D shackle is provided and replaces the forward outhaul sheave clevis pin in the gooseneck casting and is where the fixed end of the wire is attached.

The block in the bottom left hand corner of the photo is swaged to the actual outhaul wire. That wire continues aft then exits the boom as usual through your existing sheave in the boom end casting.
