The Navtec U-Bolts used to attach the shrouds to the deck on many Ericsons are similar to those pictured below. The original has a crack starting at the middle of the radius of the bend. I have found at least three (out of 8) that have at least one crack and the one pictured has a crack on both bends. All 8 are 1/2 inch (12mm) diameter on my boat.
As stated in other threads, RigRite makes replacements for the Navtec U-bolts. Here is what you get from RigRite for $289. And here is how they compare to the original.
