  The breakup of $^8$B on $^{58}$Ni below the Coulomb barrier was measured
recently with the aim of determining the Coulomb breakup components. We
reexamine this reaction, and perform one step quantum-mechanical calculations
that include E1, E2 and nuclear contributions. We show that the nuclear
contribution is by no means negligible at the intermediate angular range where
data was taken. Our results indicate that, for an accurate description of this
reaction, Coulomb E1, E2 and nuclear processes all have to be taken into
account.
