This invention relates to a fifth wheel stand as used for hitching a semi-trailer on a railway flat car for over-the-rail hauling of such trailers and is especially directed to a system of repair for the fifth wheel, or top plate, of the hitch which includes a shoe, or insert, that is welded into the king-pin slot of the top plate to replace metal removed in the repair procedure and thus restore the king-pin slot to specified size. The insert preferably is made from hot formed bar stock, but also can be made as a casting, or can be formed as a forging.
