I just acquired a PDP-11/84 that didn't come with a console panel.
That should have a 25-pin D-shell connector for the console serial
port, a baud rate selection switch, and a forced dialog switch, with a
single 20-pin connector for a ribbon cable that attaches to the
KDJ11-B and MDM. The part number should be 54-16508-01 according to
the manuals I have seen, although the only hits I find online have it
transposed as 54-16058-01.
If you have one available let me know offline in private email how
much you would want for one. I'm located in the Seattle, WA area.

I am probably wrong, but the part number on the cabinet kit for the
serial port with the 25-pin D-shell connector for the PDP-11/83
that I have is 54-16023. About 1/2" to the right is a second
number 54-16022-01C1. These numbers are on the solder side
of the PCB board. Also stamped on this board in ink is the number
7021150-02-Rev A1. In addition, there are TWO ribbon cables
which connect to the quad board, a 20-pin cable AND a 10-pin
cable. I may have another cabinet kit somewhere that looks the
same at first glance, but has different part numbers. If I find it,
I will reply with those numbers.
As far as I can remember, all of the quad PDP-11/73 and PDP-11/83
CPU boards use the same cabinet kit since the only differences between
the two boards is the J11 chip version and the clock crystal which
supports running the PDP-11/83 board at 18 GHz rather than 15 GHz
for the PDP-11/73 with an older version of the J11 chip that had a
problem with floating point when run at the higher speed.
Finally, since the quad CPU board for the PDP-11/83 is the identical
board used in the PDP-11/84, I would expect that the same cabinet
kit would be used for both systems, but naturally I could be wrong.

If you can't find a cabinet kit somewhere, let ne know in a few weeks
and I will look to see if I can find the second one. I am in Toronto,
so shipping would be much more expensive outside the USA.

This manual shows two ways that the 11/84 console SLU panel can be mounted:
http://www.bitsavers.org/pdf/dec/pdp11/1184/EK-1184A-TM-PR2_May85.pdf
Page 5-40 (page 245 of the PDF) shows the 11/84 cabinet style console
SLU panel where it is mounted on a separate rack width panel across
the rear of the cabinet.
Page 5-41 (page 246 of the PDF) shows the 11/84 box style console SLU
panel where it is mounted internally in a dedicated cutout on the rear
of the 11/84 box.
It appears that the actual console SLU PCB would be the same either
way it is mounted.
I don't have a copy of the corresponding maintenance manual for the
11/84-E. The 11/84-E power supply is located at the rear of the box
and there is no dedicated space for mounting the console SLU or any
other bulkhead panels.
So what I would really like to find is not just a bare 11/84 console
SLU PCB but also the rack width panel to mount it in the back of a
cabinet.
I have an H9645 cabinet that previously held an 11/44 that I would
eventually mount the 11/84. That would make it what is called an 11W84
widebody system as shown on page II.16 (page 175 of the PDF) in this
catalog:
