I always thought the difference between the B and C was the propeller.
Aero Products and Ham Standard


The only real difference between the P-51B and the P-51C is the factories in
which they were produced. The P-51B was made in Inglewood, California,
and the P-51C was made in Dallas, Texas.

I believe you're thinking of the P-51D/K. The P-51D was produced with a
Hamilton Standard propeller and the essentially identical P-51K was built
with an Aeroproducts propeller.
