I am trying to find out the specific year, make, and model of the motorcycle ridden by Tom Laughlin in the 1971 film "Billy Jack." I'm fairly sure it's a Triumph, but I don't know much more than that. I'm a fan of the movie, and have been looking for a weekend project. Seems like finding and restoring that particular bike would fit the bill perfectly. Any help would be GREATLY appreciated. Thanks, Greg.
