Now here we see why I would rather look at angle of the hinges than go by the numbers: while Con has #1 on the top, my 1979 B1700 has #1 on the bottom (and #2 in the top position). Mine are in the correct positions, but I'm sure Con's are as well. It may have varied by factory, by year, by batch of hinges, or by the mood of some installer, for all we know.
Update on Edit:
Even with Con's correction (next post, below), I would look at the hinges to make sure the position made sense.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.
