I made the change about a year ago. I think the block placement depends on if you will sail 2 up or not. If you will not you can put the cleat fairly close to the mast and the block can go on the spin pole. If you will be using the jib, the cleat is placed just outside the jib traveler and the block goes on the beam under the jib traveler. I used a new spinlock and it has worked flawlessly mounted directly to the beam. I have a picture but have no idea how to attach it to this post.
