I have a CalP 24 1984 and lost an end stop and an adjustable stop from my traveler. It was made by schaffer who no longer deals with 1" tracks. I have tried schaffer, rigrite, and a few custom places, and looked everywhere online to identify a real boat junkyard. I have taken measurements and sent photos.
I dont' know what else to do?
Have you considered a line adjustment with some kind of cleat on both sides. Tie a knot on the trimming end of each one so the traveler won't fly off the end. As an added safety feature you could make your own stop using the mounting bolt on each end. This should be fairly easy and it will also work better than before.
