Based on the pictures in Jeff's number 14 reply, the fender bolt appears to be of the assembled washer type, so is this discussion about two washers and a bolt, or one washer one regular fender bolt? So far, I see no measurements, just pictures. That would be a start. I expanded the picture in reply 20 (I have a 24 inch monitor) and measured the washer diameter, the "second" washer diameter and the hex drive of the fender bolt. Assuming the hex drive is 1/2 inch, the inner washer is around 0.800 inch - real close to the nominal 13/16, or 0.813, inch diameter of the regular fender bolt, and the outer washer is around 1.090 inch - real close to the nominal 1.125 inch of washer 44725-S2 which was used as a spacer. According to assembly line practices in San Jose, the first and last bolts of the top six fender bolts were "loosely" attached to allow fender adjustment to the hood and door (they were tightened and the remaining four were installed). Did Metuchen follow the same practice?
Using the previous as a guide, and the fender adjustment washer on the wrong side of the fender, the finish would be -S2, which was part of the original question.
My main point is that the objective of the forum is "concourse" restoration, and more and more "deviations" per plant and time period arise. In judging, how is this handled when judging is supposed to be against a standard? If deviations are noted (like the tire label on the glove box door) and included in a judging package, would that be advisable? Or does all this fall on deaf ears?
