Wasting a few minutes with good old Google advanced turns up an August 3, 1972 episode featuring Blyden and Gillette along with Henry Morgan, Sales and that Francis woman. A Miss Terry Giasi owned and ran a gas station, though one would hope that in 1972 this would also mean she would know her way around the inside of a car. I'm not seeing any video to confirm how she looks, though. Good hunting.

PS: Bob, while I've got you, I'm trying to place your avatar -- she was in some political uproar, I think.
