As a fairly late running change during the '32 model year a reinforcement was added to the inside of the cowl at the base of the A pillars for the then-stated reason to prevent stress cracks developing at the base of the A pillars which were evidently showing up on some vehicles produced earlier in the model year. The affected vehicles were all closed cars, convertible sedans, closed truck cabs, and panel bodies.


That suggests that unless you have a late Tudor body with the reinforcements welded in place then you may well run a risk of damage resulting from overdoing your tightening showing up down the road.


The hinge pin splines hold the pins in place, both to prevent their working their way loose and to prevent them from turning.
