Sold all those, then had 3 people from Oz all want them at the same time so I got another run done. I have them ready to go. Just shipped one to japan yesterday with the last set of adjustable cam gears I had.
It bolts to the stock crank pulley. You must make your own VR sensor mount. No cam sensor is needed unless you are trying to run sequential ignition/injection. It will not fit an ATI pulley. ATI has a different bolt circle than the stock pulley.
