capacitor legs

I noticed one thing about the new dual run capacitors I bought:
fan has two legs, compressor has three legs and common has four legs.
can I assume the same for old dual run caps?
sometimes, it's hard to see the label when rusted.

If you are having difficulty determining which terminal is which on the old cap, trace the wires.
