The valve repair kit includes 2 each of the standard and button flappers that will provide enough to replace any requirement of V1, V2, V3 and V4 valves, with the exception of pre-1998 versions of V1 (replace with new V1 valve). The valve arm and link will not fit the older RCV-75 valves, but the standard flappers, O-rings and cable mounting bracket will fit all with above mentioned exception.
