Ray,
I had the same problem with James Bond's Little Nellie gyrocopter - can't find decent reference photos anywhere.
Does your local video store have the Dukes of Hazzard on video or better yet, DVD? If so, get one and there'll almost certainly be shots of Daisy's Jeep sometime during the episode.
My father in law has a DVD player on his computer, and we just rented "You Only Live Twice", found detail pictures of Little Nellie and did a screen shot and saved it to the hard drive.
Cheers,
LeeTree
