    Torsion keys will they fit

    I have a 93 k3500 I'm putting new stiffer torsion bars in, I have a set of upgraded keys from a 01 3500 4x4 the guy put in for plowing I can get cheap, will the gmt800 keys fit in my gmt400 though? I have been told by some they will, others no they are indexed differently?
