Hy Grover, If I am understanding your problem the holes in the center of the thrust washers are too small to allow the kingpins to pass through? If that is the case then you will have to enlarge the holes until the kingpins have clearance. Did the thrust washers in question come with the kingpin kit? If so I would say they are the wrong washers for that kit. Being that you are under the gun to get the truck back together just modify the thrust washers to fit. I would take some before and after pictures of the thrust washers with some kind of a measuring device in the picture to show the kit supplier what you had to do to make things fit and hopefully get the correct washers supplied or a rebate on the partial cost of the kingpin kit, hope that helps.
