The larger of the two sizes was also shared with the D16’s. I’m not sure about later D15 motors, but my guess is Honda might have kept doing the same thing. You might have to go though some junkyards or have some people check some swapped out D motors. I’m sure there is a pulley out there with the smaller hole and setup for power steering.
