Re: Adapter Plate Thickness

If the M119 has a rear main seal holder similar to the M116/117 engines, the rear face of the crank flange (the flywheel surface) is approx. 20-22 mm behind the rear face of the block. A 3/8" thick plate (9.5mm) would be well forward of the flange/flywheel line. Is the anticipated flywheel stepped forward? Most flywheels have either a flat forward face, or are stepped aft.
