Does anyone have a photo or mechanical drawing of one
of these things?
There are several kinds. These:
http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/jpg/H960FrontPanelClips.jpg
are some of the better ones; they are connected to the rack via countersunk
screws (go in the holes), and have embdedded nuts for use with the blank
panels which have the matching captured bolts.
The 'usual' ones don't have the embedded nuts, just the two ball/post things
on the ends, and to attach them to the rack, they have (on the back) a pair of
prongs with a fishhook-tang-like capture device on them.
The back prongs were an even bigger crock than the ball-and-post things. The
latter at least worked, even if they did occasionally break; the prongs
wouldn't hold for s^*&^(*.
I'll look and see if I have any of those, to take a photo of.

Anyone have a broken one they can send me for Evil Experiments? :)

I think there are other ways to produce this than a one-piece molding, if the
aforementioned RC balljoints aren't suitable replacements.
I'd take some nylon, acetal, HDPE etc. threaded bar stock (plenty on eBay) and make a
form tool for the ball and post combined, then knock them
out on a lathe. Tap the block for the thread. The most time-consuming part in this would
be the form tool profiling, but being soft material
you could get away without the need of grinding a HSS toolbit.
I've got some nylon bolts and my trusty Unimat lathe so I may give it a go to see if
it works.
Steve.

my take on these would be make them out of soft metal,(Al) thread the post holes and use a
threaded post with a
recess for either a "O" ring or tubing to hold the panel.
