Ok on the old flywheel (OEM) there is a secondary ring plate which is used for the crank position sensor. On my new stillen flywheel it doesnt have that plate nor does it bolt up to my flywheel. Any thoughts? Get back to me asap..

 

well you need the backplate for the car to start, on my fidanza flywheel it bolts right up so i dont know how to fix it for ya all i know is you need it for the car to run.
