Hello all, I need a fuel pump drive/eccentric for my 64 riv, 425. It is the round disc that is mounted to the end of the camshaft that pushes the fuel pump arm. My fuel pump came loose some years ago and when I recently tore the motor down, this part was badly worn. Also looking for a right exhaust manifold. Thanks, I have owned this baby since 1981 when I was 17. After over 100 cars it is the only one I have really enjoyed and kept. Thanks, Paul, San Diego
