well I called up a buddy of mine and he informed me the gear that I had ordered was actually the h22a4 gear which has a crankshaft positioning sensor, hence the key built onto the back of the gear... I wasn't aware of this seeing how I told the guy I wanted an h22a1 gear. Oh well, live and learn. I got a new H22a1 gear on order and should be able to continue putting this frankenstein back together soon.
