I have to go with NO here.

I am a big Rockford Files fan, so it was cool seeing Gretchen in "Study in Rage", even though the episode wasn't that great. Gretchen looked just like she did in the "Rockford" episodes. In "Uncle Kevin", the woman thought to be Corbett does not look exactly like her, which contradicts how she looked just like her Rockford charater when she appeared in "Rage".


Gretchen Corbett was in The Rockford Files from seasons 1 through four, spanning from 1974 through early 1978. Her final episode aired on January 6, 1978. She left after season 4 due to a contract dispute. She was not in every episode. She was in 33 of them in about 3.5 seasons worth of appearances -- averaging a little under 50% of the time.

I am surprised NBC allowed her to appear on Five-O, on a competing network. "Rage" aired on February 11, 1975. That's during Rockford's first season. Five-O and Rockford weren't competing yet (this would start in the 75-76 season, hurting both shows due to their similar audience), but I'm still surprised NBC allowed it.

If she did appear in "Uncle Kevin", it would have been before Rockford started. That would make it a bit more likely that Corbett would have taken a very minor role, as she was not yet famous at the time. However, I still don't think it was her.

Corbett looked older than her age at the time. She's now 77, and in fact was born very close to when my mom was. She's still alive.
