Hello, we just raised the main for the first time this year and the little Delrin balls in the mainsheet traveller car apparently turned to dust & chips. The owner's manual says don't take the car off the track because I might lose the ball bearings, but I want to put some new ones in. Does anyone know how to rebuild the traveller car? Do you know who makes (made) it? Anyone know where I can get a rebuild kit?Any advice would be appreciated, thanks.-- John & Judy Griffiths SV Pegasuslying San Carlos, Sonora
