I contacted him about 3 months ago, about the same thing.
He wrote me that he lost it in a puter crash.
I dug around and finally found it on one of my old hard drives. I sent him a copy of the sock morph.
He told me I could distribute it if I wanted.
I don't have a site to do so though.
Now that I sent it to him, maybe he'll e-mail it to you.
