SLU's backpanel for one BA11-SB box (PDP-11/23 PLUS)

[SPC]

I want to purchase in a few days from now one BA11-SB enclosure (tabletop
type) to swap all the boards of my PDP-11/23 PLUS (my actual enclosure don't
have a box cover). But there is a problem: The box is prepared to put a
couple of mini back-panels, I suppose with the intention of put a couple of
rs-232 ports, or another kind of connectors (network, etc)... but there are
no panels.

I believe that I saw something similar for one PDP-11 24 some months ago but
I'm not sure.

Trying to avoid homebrew solutions... someone knows about a product from
Digital or 3rd party for this purpose ?

Kind Regards
Sergio
