All 1964 onwards engines (every powertrain combination) except 95/MT came
with a harmonic balancer. Not sure if 1964-'65 FC 95/MT gets a balancer,
tho-

There are 2 part numbers for the harmonic balancers- its the same part
exactly, however the ones that tested to best 'pitch' attenuation were
cherry picked for the 140/150/180/FC. Its designed to cancel a ~220Hz
signal, which is about "middle A" on your piano. Each ones a little more or
less 'on key' and the best ones got the HD part number.
