I have an '86 25.5 that the traveler will suddenly slip when under a heavier load due to the fact that the pins that secure it tend to slip out of the holes in the rail. I wish to upgrade to an adjustable traveler and had found a website selling an upgrade kit that did not require a rail replacement. Does anyone know of this kit or another possibility? I did not bookmark the site and my searches do not find it anymore. I could purchase a complete Harken kit but that would require the rail to be replaced and I am trying to avoid that if possible. PS: I thought I had posted this a few days ago but cannot find my original posting, so I am resubmiting it....ThankKen
