    1940 BT horn mount hadware

    Corso kits have cad screws & nuts
    Palmer says #031 screws[horn to mounts] cad,everything else parkerized
    Corso #4862-31 curved spring plates have .265 holes,OEM .220..
    Corso plates look stupid,holes way too big
    Corso holes 2.580 outside of hole to outside of hole,OEM 2.600.
    .Corso does not slide over screws,too tight,OEM fit nice
    Palmer says lock washers on upper & lower mount screws,
    OEM 1940 parts book does not show lock washers,only nuts
    OEM 1948 parts shows locks
    Anybody know if they originally had lock washers on 1936-40?
    Also 1940 book shows 066 as 5/16-24 X 7/8" later books show 066 as 5/16-24 x 1" to mount upper bracket to fork.
