Thanks guys.
So called the guys at NPC and the HD single plate organic seems to be the way to go.
Would still be interested in the Xtreme twin. Might give you a call Richard to see how it feels before making up my mind. Do they come in pull type rather than push otherwise I'll need to factor in the conversion kit too.
Seems like it king to be around the $660 mark for install of clutch and flywheel but may as well get other fluids changed out at the same time (atessa, gbox, t. case and diffs).
Thanks everyone
