If Scott's book reads the same as mine, I'd take that with a grain of
salt. (IOW it may not be correct.) My book also lists all three P/Ns,
with no crossover figure. However, the footnotes state "Interchangeable
items are marked with *", and there's no asterisk next to the dimmer
switch bracket numbers.
Plus, just a few lines above, two different screws are listed for the
grab handle attachment, and I do not believe they interchange.
