The hole on mine at the upper arrow is too big to accept the wire clip. It looks like possibly there should be a speed nut there for the clip to go into. Is this correct?
Nope no nut nor does the small T shaped white retaining clip have provisions for a nut. The end of the clip that passed through the hole should have two ears that catch the inner part of the hole. Maybe the ears are broken from yours
Looking at the mounting hole and the witness mark on the lamp housing it appears to have take a #8 pan head self tapping screw. Would it have been phosphate and oil or chrome?
For San Jose I've seen them phosphate and zinc. No chrome
I see the word READY stamped on the deck lid. Mine had the word ALTER there. San Jose car. Was this a person's name?
What your seeing is HENRY a short Mexican fellow that went to work at Westinghouse in the bay area after leaving Ford. Have a good friend that worked with hime there and even got his inspector stamp :0
You may be seeing only part of the name with "ALTER" since it does not look like other names I have on record. DId you take a picture of it?
San Jose, starting in mid-late 68 used the inspectors last names (Usually - except for Henry - since his last name was too long)
