I have a complete wiper assembly for all 1951-52 Ford trucks . I believe it will also fit 48-50 models but not totally sure on that as there were some changes to the cabs for those years, This incudes every thing from the motor arms, to even the pieces that hold the wiper arms, You will need a new cable from the knob in the dash to the motor but this is an easy fix and most dealers have this cable or you can easily make your own $150 Plus the ride which is $21.10 OR you pick up with a mask. Happy NewYear guys Tom
