the crank is a LA Enterprise Kyptonite 3.875'' stroke.
since the flywheel is only being used on the run stand, is it possible that at least 3 of the bolt holes on the flywheel would line up to the crank holes? it won't see anymore then 1800-2000 rpm on the stand. if 3 bolts holes lines up, that should work?
I couldn't tell you for sure- I don't have any of the 8 bolt Gen2 pattern stuff sitting around right now. Best way to tell for sure is to slap it on there and see how many you can get to line up. Center registers should all be the same.
