Chance
Initially I was planning on using sex bolts to hold the sheeve assembly in the stainless bracket. They look like the first picture below. I was going to file a small round area for the head to slide through and that would be that. But it occured to me that to change a sheeve should one fail I would have to remove the bracket to do it. So I decided to just use a couple of 5/16" pieces of round rod with cotter pins which would allow me to remove and replace a sheeve without taking the entire assembly out of the mast.
