That was listed in some official publication of her credits in the 1970s or early 1980s, if I recall correctly, but I have never been able to find her listed for any episode of this series.
That doesn't mean that she might not have had a minor role in one of the shows, as she did on Kojak or, supposedly, Class of '65 (another show where she's not listed in ANY of the episode guides published, and I've checked more than one).
And then we come to Search... Darling, sometimes I swear I hear her laughing whenever I try to track this stuff down!
Good Luck!
