55.2-59 King pin thrust washer assembly

[cansled]

I have read all the posts on this form regarding kingpins, The one thing I can't figure out is the assembly and order of the brass thrust washers on my 1956 3100. In the original shop manual it states there should be a thin washer between the two thrust washers facing each other like a sandwich with a thin washer in the middle. However the speedway motor instructions state that the two thrust washer should be facing each other with no mention of the thin washer in between. The kit does come with washers to use as shims but it also comes with two smaller washers that would fit inside between the brass thrust washers. Anybody have the proper information on this. Thanks.
