Hi Bruce,
I've been threatening to call you for a few weeks.

I'll prioritize it for this weekend.
I suppose a way to tell if a box was painted or not is to look at the scalloped portion that faces the chassis since this area would (theoretically) be more protected. However, even if one box (or a 1000) is painted or not, is not an indication (to me anyway) that
all boxes would follow suit. Again, without documentation, I would not judge a painted or unpainted box as a concours deduction.
The E/flasher wiring is a similar example. Thanks to you, and verified by 4 other 69 Spider owners, there are two different E/flasher wiring schemes for the 69 although currently known Alfa publications state only one. In other words, all cars may not have been built the same nor may there be published documentation on any changes. The difference between the steering box and the wiring though is that the wiring will not fade nor disappear over time. And since there are (at least) 5 known examples of cars with unpublished wiring schemes, this to me
is the documentation.
