I think I agree with you. Before working on it today I measured as close as possible without taking the bolts out. Mine are the 58.8mm bolts from the factory. You cant go by the ZL1 guys pictures that protrude by about a 1/4" through the hub flange. That was why I asked parts if the new bolts were the same length as the ZL1 bolts ( they said its the same part #).
I think that is why the TSB does not apply to 2018's, they are the longer bolts. The flanges must be thinner on ZL1's, or the bolts are longer than the TSB bolts. not sure which.
