Odds are the Mustang would be firing down on the helo, towards the more
exposed critical components. Most of the armour would be
positioned for protection from ground fire underneath.

If the helo was flying low/NOE, it'd be a brave Mustang pilot who made a
diving attack.

It happened many times during WW2 and Korea just not against helicopters. Have
you never heard of a strafing run? P-51s made a lot of runs against low flying
aircraft as well as stationary targets.
