    you will need to use the one that has the straight shaft

    the difference is on the inside... the straight shaft one has the splines 2" further rearward that the one with the flare

    Yep top one is for 30" shaft without 2" pump spacer. Bottom one is for 28" shaft or 30" with the 2" pump spacer.
