Narrowing a Dana 60.What length axels?

I have a Dana 60 I,m getting narrowed to the exact width of my narrowed 8 3/4.My 8 3/4 is 46 5/8(basically 3 inches off each side of A-body width 52 5/8)My axels are 25 inches(A-body with is 27 11/16)in the narrowed 8 3/4.I,m gonna run a spool in the Dana,so if my housing is 46 5/8 inches wide,can I just order 2/ 25inch axels or is one shorter than the other due to the center section offset?Some have told me both axels should be same length,others say no,one is shorter than the other.Any help would be appreaciated before I order axels.Thanks:book:
