Bingo. That's the external portion of the front bobweight.

Not that I know of.

As far as I know--the SV flywheels are drilled for both 11 and 12 inch
clutches. The 4 cyl flywheels are drilled for something smaller (9" ??).
The SV flywheels have a cast in bob-weight--a deliberate imbalance--on the
engine side of them.
They MAY have a different crank flange bolt pattern, 4 vs 8 , I don't
recall. (Tom M ???)
The SV flywheels use eight bolts and a dowel, and will only mount to the
crank in one position (wise, because the bobweight imbalance needs to be in
the proper location).

Yes, I believe they are.
BTW--just for irrelevant trivia--IH did the rear external bobweight
differently on the LV8 engines (401/461/478/549/537/605)---all of the
flywheels/flexplates for those engines were neutral balance, and the rear
external bobweight was a separate piece that mounted in between the
flywheel and the crank flange.
