Rolf and Tim - thanks! I was actually about to ask where I could get those bearings cheaper. Thank god I don't think I need a new car... that's like $60 right there!

Simon - the stops at the end of the traveller are intact, and I had run a line to prevent the car from reaching either end. Can your cat use a stainless steel car? I really wish mine could... the Harken car is a bit chinsy. Does anyone know if that's an option for the Nacra?
