Re: !939 spun #2 rod bearing
I don't know about 'trunk' engines, but 48 was the first year for 8BA engines in trucks (pickups), and I'm pretty sure all 8BA's had/have inserts. There are also some 59's that came with 8BA internals (includiing insert rods).
To address the question, almost any damaged crank can be repaired. Sometimes easier to find another crank. Generally, rods can be 'reconditioned', sometimes replaced.
