Spare parts
Well - if they didn't destroy it as they removed it, you now have spare forestays, backstays, etc. Do you need them all? Probably not. But in an emergency, or as a stand-in while some other maintenance is being conducted. I ended up keeping two of my old shrouds when I rerigged the standing rigging. One is a spare and the other I plan to cut up and use for various other things such as a emergency cable on the outboard - make sure it stays with the boat if it came off the mount. However, if I do use it for that, I don't have the skill to make new "eyelets" on the ends of the freshly cut wire so will have to pay someone to do it for me. It might be more cost effective to just go out and pay for a new cable.
