Conversation Between SPEC-01 and Rayzor Rigzz

Hi, Ive been looking to buy the spec stage 2+ clutch to put behind my twin turbo 5.3L vortec truck motor, I was just wondering if you could give me a part number for that exact one to make sure I am not overlooking anything when searching. Also what is the weight of your billet steel flywheel that it has the option to come with, and what is the weight of the aluminum one? Thanks in advance, Ray
