I would be interested in a kit if anyone is able to setup a deal. I haven't had any luck contacting them. There was a mention earlier that tremec has the parts to do this. I have an email into their tech help address, if I don't get a response I'l start calling them.
Boxhead,
If you search the forum on t56 you should find a thread that mentions a place in australia that does this mod.
