Narrative:
Gusty wind conditions. Upon flap extension from flaps 20 to flaps 25, flap and slat disagree indications occurred. I elected to go around. ATC vectored us clear of traffic. We accomplished the abnormal procedure, requested crash fire rescue equipment due to 'non-standard' confign, and landed uneventfully.
