The problem here is the fact that the cheek block on the left is no longer manufactured and it has a unique trapezoidal bolt pattern. We’ve had a few Nonsuch 22 owners approach us for replacements because of failures like the one on the left. The replacement on the right was fashioned after some of the later model 26’s and 30’s but scaled down to fit the existing bolt pattern of the 22. These are used for the upper choker block on the mast only. Replacements for the wishbone will be developed soon.
