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.

Does anyone have a photo or mechanical drawing of
one of these things?
There are several kinds. These:

The balls remind me of rod-end linkage stuff (this for the RC hobbyists):

But I don't have any idea of size. But a good engineering findings
catalog might turn up something closer.
