Noel,
What pdp 11 do you have now? Any progress on the 34?
I have my 40 taken apart wirh only the empty card cage in the rack. If
you're in the area you can swing by to take measurements.

IIRC that 21" mounting box (and I assume therefore the fan assemblies)
was used on other machines like the 11/40 (some versions), the 11/70,
etc. I am not suggesting you raid one of those for parts, but it might be
something else to look at.
Yes, AFAIK, these were on all 21" boxen (BA11-F ?)
I do have an 11/45 here with the original fan
trays. The top one is easy
to get at and measure, but IIRC the bottom one is a right pain, involving
removing all the boards and dismantling the very fragile card guides.
True, unless you simply remove the entire fan box from the bottom of
the card cage. Have a clean floor, you will have to lay on it, as a car
mechanic :-) The box is (AFAIR) mounted on the card cage with 4 or
6 (?) screws.
