These photos are after the rebuild, and the restorer's phosphated studs and zinc plated nuts are about the same as I found, but the washers are incorrect. The nuts do show Gr 5 marks. Note that the flanged shaft is phosphated. According to the restorer, the new markings are also correct, because, he said, Eaton had several formats for marking. I asked him to change the date code for appropriate to my car's build date of about mid November 1968, maybe September 10.
