I have been searching around for info on an LSD or insert for a 8G auto. I know about Quaife but was thinking that all I need is an insert. I found something about "phantom grip insert" but can't find a site on it. Or any other info. How much are these guys, and anyone know a site for it. Or the name of any other inserts I could get.

I have an 8G auto GTZ, if that matters.
