I want to upgrade the traveler on by beneteau 1995 M510. The original traveller is a french amiott. Amiott does not produce a car with ball bearings. Do you know of a car that will fit the same track? Its a curved T-track 1.25" wide 2/16" deep. I'm told the 600 sq.ft. sail requires a car able to take 8300 lbs of pressure. Alternatively can you suggest a reasonably priced replacement for the track and car. e.mail: SLceladonhome@msn.com
