We continue our study of the astrophysical implications of the linear potential V(r)=-βc2/r+γc2 r/2 associated with fundamental gravitational sources in the conformal invariant fourth order theory of gravity which has recently been advanced by Mannheim and Kazanas as a candidate alternative to the standard second order Einstein theory. We provide fitting to the rotation curves of an extensive and diverse set of 11 spiral galaxies whose data are regarded as being particularly reliable. Without the assumption of the existence of any dark matter the model is found to fit the shapes of the rotation curves extremely well, but with a pattern of normalizations which proves to be very instructive.
