hi James
Deflections with sensitive eqpt can be confusing. Everythng deflects even under slight pressure. But a .005" clearance would be quite generous even for oil cushioned plain bearing. many rear mains have been replaced alone. Can try rolling over pieces of shim or card. To go further is not a huge job unless you find a cracked crank, cracks in be bearing metal etc. If you are not intending to drive to Peking, can risk a crankcase, and do not have a pile of spare money, often prudent not to look!
Many cars have gone long way on the spiral seal. OK unless worn. Slinger between flywheel must be present.
