I would check the rest of the rigging. If 2 lowers have gone ( they are less loaded than the cap shrouds) then check the rest. Doing rigging is a lot less expensive than you think. I just replaced the standing rig on my morgan
OI 41 ketch
( 12 stays in total) for only $3800 CDN taxes
included! You don't have to pay a rigger to remove your stays. just take them in an have your rigging shop replicate.
Occasionally you might have to upsize the holes in your tangs. I have to go from 1/2 to 5/8 pins on my cap shrouds, but the original tangs were massive and had plenty of meat. My rigger even said it was OK to do so
your mileage may vary. all depends on your confidence level working on your boat!
