To confuse the matter further ... I just viewed a clip from Missing Reward featuring Stacy Keach, filmed in August 1991.
The clip featured Carl Probyn, playing the part of himself, jumping on his bicycle and peddling up the hill, and includes a very quick and poorly filmed scene of Jaycee screaming as she is being pulled into the left side of the car, over the lap of the driver, and onto the passenger side.
Probyn stated that he insisted on doing the filming himself and said "It took us 12 hours to shoot this segment ... We did it three and four times and everything is just the way it happened".

I am unable to find a full version of this Missing Reward episode.
I looked everywhere also and couldn't find the full version. I did find this which has a very plausible reenactment (1995)
