Have I got the right stepper motors for my X-Carve?

Just starting to assemble my X-carve and I got to Step 4: Motor mounting which says my NEMA 23 stepper motors should be part #25311-04. But the motors that were delivered to me have part #30570-02 on the box. The only numbers on the motors themselves are KL23H251-28-4A, Lot no. 20150821. So before I go further in the assembly, I’d like to know for sure if I’ve got the right motors?
