I'm with sd on cutting the ends off and putting on new fittings, but I suppose that would ruin the "traditional" look of your rigging? So trimming down the bolts would work.
More problematic is that if the rigging has stretched out that far, it may also be unsafe. The recommendations today are to change standing rigging after 10-20 years, depending on the service and condition. Or, if you run a cloth up the wire and you find ANY meathooks--replace it. Any meathooks at all mean the cable is failing.
Sometimes you've got to make do...but how much stress will this trip put on your rigging, and what could a rigging failure cost you?
