According to a service manual I have the end play for a 235 engine can vary from .007 inches to .009 inches. (0.178-0.228 MM)
It looks like you're slightly above the maximum end float on both crankshafts, but it's not likely to do a great deal of damage unless you're planning on hauling some heavy loads at high RPM. The rear thrust face (nearest the flywheel) is usually the one that wears due to pressure from the clutch release bearing. It is possible for a good engine machine shop to weld material onto the thrust face and regrind it to specifications, but in my opinion, you're not far enough out of limits to need that. Just use the crankshaft with the least amount of end float.
