Does anyone have dimensions of the alignment bracket that is used when
installing an AR-5 DRO scale, which holds the reading head bracket to
the scale case at the proper distance? How does it attach to the
reading head? I can't picture how it works.
Just got two scales for my '67 Bridgeport J-head, and can't find any
references in the archives other than the installation manual (which
talks about it, but doesn't show it).

Thanks much,

Dave
