The CM pressure plate will bolt right up to a Luk or Sachs modular flywheel(thats what we have stock). The guy who built my clutch just drilled out the rivits of a stock modular clutch, and then built a custom 6 puck cermaic facing disk, then bolted it together. All the pressure plates are the same..actually I believe CM and Spec, ect..use a Luk or Sachs stock pressure plate and modify it, for higher clamp load #'s. But a non mod, and mod flywheel will both bolt up to the CM pressure plate. I'm pretty sure the disk will be ok for fit too..i not 100% positive, but i think its the same size diameter as the stock setup..i dont see why it wouldnt be.. I just worry about the strength of our flexplates..Oh yeah, i can have the trans out and on the ground in about an hour and a half now :) hahah.. Much easier and faster than what you guys have to put up with
