Searching for JRC 4558D OP-AMP chips from the 80s- any leads?

Hello all. I'm brand new to the forums. I hope this is the appropriate place to ask the following question.

I'd like to ask if anyone here has experience in digging up op-amps from old electronics?

Specifically, I'm looking for an old JRC 4558D for a particular project I'm working on. I know you can find the new ones for dirt cheap on eBay, but I'd like to locate one from the 80s. I could pay $30 on eBay, but I figure I'd try my hand looking through old electronics first and, you know, not pay $30, haha.

Any one has any tips?
