I don’t think they will ever be offered for sale, and I doubt he will respond to you.
When Clay pulled them a few years ago, I seem to remember that he took some effort to scrub all traces of them from the internet. He seemed determined to put a halt to all distribution and rejected all pleas to license or sell them. It really got a bit weird in the end, almost as if he was determined to disown them for some reason.
They are out there of course, but getting them ethically is probably impossible at this point.
