Any car built before December 9th, 1968 could not be an "RPO ZL1" per GM records (additionally, there are similar records on cutoffs for order placements before certain dates not able to select RPO ZL1 as an option). Now, could a Corvette fitted with a ZL1 engine somehow escape the factory before then? That is certainly possible, but it would not have been ordered or built as an RPO ZL1. Any early RPO ZL1 would also need to have to be built with the correct heads based on the NPC production change specifications effective the date it was built.
