maybe I got the wrong washers. The black washer (which has the little lip) is not a snug fit around the inside of the larger hole. I have not measured the hole versus the OD of the lip of the washer, but there is significant play.
I have no idea how washer for the the smaller jack fit. In mine, I could just get the smaller jack in the hole (barely), but I could not get the black washer to seat. The lip of the black washer has to go through the hole, so that the jack does not touch the metal.
Are you sure that that is the case for the small jack? If that is true, then Van's must have changed the hole sizes. Or our jacks are different diameters.
