Help finding wheels - SSR GT3s

Hi all. Haven't posted in a very long time. Where is a good source for aftermarket wheels? I am replicating a car for my father in law who has 18" SSR GT3s on his 928 GTS. I've done a search and can't find anything.

Any suggestions?

Thanks - Steve

Here is a link to what they look like:

About a year ago I searched high and low all over the internet for these, without success I'm afraid... so I'm also interested to know if they're available.
