Replacement contact wire terminal for Gottlieb edge connectors.
If your Gottlieb has IDC Housings, these will fit those.
Just back out your old terminals, snip them off, and attach a new one of these.
It will slide right into the existing IDC housing.(see photo gallery)
As a rule of thumb, ANY Gottlieb over 10 years old. and I change all of these, every connector, on every board.
You will require a proper crimping tool.
