NOTES: These bolts were part of a lot of Ben-Hur trailer parts purchased by us many years ago. These parts were removed from their packaging then boxed in bulk. Their actual use is unknown to us. They measure 1-1/2″ long x 7/16″ in diameter on the first shoulder then 3/8″ in diameter on the second shoulder. Please check your manuals as each manufacturer may have had different configurations early in the war. These bolts have been stored poorly and do show some rust and corrosion. YOU ARE BUYING 2EA BOLTS. Possible suggested use is on the hand brake quadrant at the front of the trailer (I am not sure of this).
