My red car had a brand new clutch in it. 'Porter' is the only branding I can see on it. Never heard of them myself, but looks very... clutch like. It's never been used, and is still sparklingly clean. After $150 plus shipping for it, pressure plate, clutch plate and throwout bearing. Was bolted to a standard flywheel, so is standard sive, which I think is 225mm?
