5.7 L hemi into a 72 Dodge Demon

GDemon, is that Hays setup you are currently running the one sold here http://www.mopartsracing.com/parts/57hemi.html by any chance? I looked up the pressure plate part number on Google and one place listed it as a Hays, otherwise I didn't find any direct branding. I didn't know if Mopar Performance made one or not, so I wasn't sure if it might be theirs. If it isn't what you are using, has anyone used this setup before?
