Was trying to install flywheel today on my 312 , I only get a maximum of 4 out of the 6 bolts to align no matter what position I try.  The flywheel is the original but the crankshaft was replaced.  I tried a second flywheel and get the same result.   At least 2 holes look visibly off at all positions.  Are there crankshafts out there that have missed drilled holes or do I need a different flywheels?   It is a flywheel for an 11" clutch.
