As soon as I removed the end cap on my old style non captive bearing car I watched all the bearings bounce down the deck into the lake! The balls I could save are out of round so need to be replaced. My problem is getting the end car off. The flat head retaining screw wont budge. The old bearings are 5/16 brown colored so I believe they are torlon. The car lost its label long ago so I dint know if it was red or blue. Boat is Oday 28.
