The parts identified by you were to my very great surprise still available a couple of years ago.
The pods themselves are NLA and a member here gave me a broken one that I have used to make a mold. Sadly whilst I have some access to a plastic casting plant, my friend's business normally makes plastic storage jars and what our US friends call "soda" bottles. That kind of plastic is utterly unsuited to making instrument pods from without a substantial redesign (they would have to be much thicker and heavier than "stock").
It is my intention to use the molds we made to try casting some sample parts in industrial resin, a material that more closely matches the original in strength and hardness. But, to be honest my enthusiasm has waned significantly, in fact I suspect that overall the demand for the things would be very slight, otherwise someone would have put them back in production years ago.
When I thought I could simply insert my molds in my friends plant and run off a 100 or so pods from the plastic left at the end of a production run I was interested, but hand mixing small quantities of expensive epoxy, coating molds in release agent and then making them one by one has almost zero appeal.
