All the existing lines needed to be replaced. Also we found one broken sail slug that needed replacing. I did a search online and found one seller who sold the kind of slug I needed for the 40 year-old boat. See package below for details.
We only needed one, but I ordered two to have a spare just in case we broke another one.
I ordered a hot knife to cut the lines and it worked well. I used painter’s tape before cutting. I let the weight of the hot knife rest on the line where I wanted to cut it. I pressed the trigger and when it started cutting I moved it back and forth slowly. I placed a wooden board under the line so as not to burn my cooler.
