I bought a Paxton GSS couples of years back but have not get around to set it up yet. It was missing a few mounting bolts here and there.
Here is a number you could call for more inform. I was told the guy now owned the GSS serial of Supercharger.

Hope this help and let me know how it turns out. I am sure someday I will need help with the sc.
