Sorry forgot to add that it's just a Chev Pressure plate with some sort of Isuzu light truck 12" friction plate. Unsure of the specs, but like i said Doug from NPC said it'll handle 1000nm.
I've spoken to someone at NPC a few weeks ago and they recommend I get a 1hdt,ft,fte flywheel and machine it flat and re-drill it to suit a chev 6.5l diesel clutch. They said it would be 70% stronger than an exceedy safari tuff clutch.
