Toyota on the hunt for Crump's Hilux ute

Toyota is trying to track down the lead actors from a series of 1980s TV ads that featured Barry Crump and his city slicker sidekick Lloyd 'Scotty' Scott careering cross-country in a ute.
The TV commercials were for the Hilux, and now the company wants to find the two original bush-bashing river-running trucks that featured in those ads.
One is a red 1982 Hilux, the other a 1983 model in yellow, complete with red and black stripes.
The search is part of the company's new advertising campaign, and may feature in a new commercial if they are found, and still relatively alive.
