So, I have an Apple ][+. It is missing an IC at

I don't know why. it used to work... I think my mind is going. I have no
memory or removing it. Anyway, I need another one. The board is marked
74166.
Can I put any shift register IC with a similar part no, like this one:
74166PC | FAIRCHILD | IC DIP-16 Shift Register (icompplus.com)

in there, or ?
Thanks,

I have a mobo that has that very part (Fairchild 74166PC), so it's a
good bet it'll work.
