Parts book shows related parts but doesn't show the backer plate (see attached) Service manual says axle shims, then the brake backer plate against the shims, then what they call the "backer plate reinforcing plate", part book calls it part 1002-24, "washer and retainer". So is this the correct order for assembly, shims, then the backer plate, then the part 1002-24?
Also, what is gasket 1002-31 made of, the book calls it "paper", mine was destroyed but it seemed like more of a cork material?,,,
