Believe the question related to the #2743 but been wrong before Take notice of reply #15
In reply #15, mhubert equated the DSO item number 2743 with the dealer location in Sault Ste. Marie, which is not the correct association. Jim tried to sort it out but didn't quite have it right. Your answer that the item number and the DSO number are different is correct, of course. My intent was to provide a more comprehensive explanation of the difference between the two numbers, and to highlight that the district number is part of the dealer number for those who were unaware of the fact.
What's funny is, the whole discussion of original delivery location and whether the car was built with smog equipment is all based on a misinterpretation of Dudly's comment about "California smog". He was making a joke about
actual smog in the California air being the source of the black in the air cleaner. But we're so used to using "smog" as shorthand for "emission reduction equipment" that we started discussing the connection (or lack thereof) between emissions equipment and the air cleaner interior.
By the way, I found the attached scan of a 1966 owner's manual (model unspecified) showing the Milwaukee DSO included the UP. Graphic is from
