    all 10.5" 14bff's have the same spline count which is 30 IIRC

    For clarification, full float 14 bolts are 1.56" 30 spline shafts and 14 bolt semi floaters are 1.41" 33 spline. Check whether or not your axle has full float hubs.

    before the "Small" 30 spline shaft thought goes through your head
    the perpetual breaking dana 60 30 spline shafts are MUCH smaller than the 30 spline 14 bolt shafts

    I only mention this because i wondered at one point also how the 14bolt was indestructable at 30 spline and the dana 60 snapped like a twig at the "Same" 30 spline count

    then it was explained to me the difference in the spline sizes between the two
