In my mine it would be more likely in a modern truck with today's automated manufacturing techniques. Maybe he is correct and maybe there is someone out there who knows for sure.
Britcon: Maybe the '40 is different, my cowl vent lever has a very strong detent that holds it in several positions including shut. It could be they were used in earlier years for springs and not eliminated when no longer needed | | |
