if it's possible, i would not send his rec to fordham from lsac. explain that it's your top choice and ask him to tweak that letter just a little bit to include things specific to the school-- even if it's just recounting something specific about his own experience and explaining how confident he is you'd thrive there for similar reasons. if he writes that it's your top choice, that might carry more weight than you saying it is, b/c you could say that to every school.
it's also worth telling him on the off chance that he maintains a relationship with anyone there, b/c if he really likes you it might make him pick up the phone and mention your name to someone
