Based on the registrations, my educated guess is that 174 will be converted from 76L to 76Z & 181 is going strictly for maintenance and not mods. I could be wrong about both. 1704 (N174DZ) should be the ship returning from CAN early next week and it'll be in the 76K configuration.
181 should become a 76K. 174, as a 76L, is interesting and could be a maintenance-only visit.
