I have an old sailboat and there is a traveler car with 8 tiny bearings (R3A-2RS to be precise), which holds the backend of the the boom to the boat. The bearings fell apart after 40 years of use. Navigating the web I found the Boca Bearing website and fairly easily found what I was looking for. Ordering was easy, I received order confirmation via email, and the bearings shipped and arrived as Boca estimated. I need 6 more of those bearings. Thanks.
