Thanks Jim, Nightmare 1974. I'm going to label my Stroppe a 1971. Found the info below on the Screamin Demon(1966). Just need a year for BC Racer.
Amid rumors of its possible return to the showroom, Ford’s beloved Bronco sport-utility vehicle will be commemorated during a special display in the Nationwide Showcase Pavilion during the Sept. 24-27 AutoFair at Charlotte Motor Speedway. Trucks in the exhibit will include a Bill Stroppe Baja edition, a freshly restored classic Bronco, and the Screamin’ Demon—a 1966 model updated with a Ford Mustang powertrain.
Tom Broberg, co-publisher and co-owner of Bronco Driver magazine, will display his publication’s Screamin’ Demon project at AutoFair. The truck is a first-year Bronco, wearing Ford’s Screaming Yellow paint, and powered by a 2007 Mustang V-8 engine hooked to an automatic transmission. The 300-horsepower, four-wheel-drive Screamin’ Demon has reached 110 mph, gets 20 mpg on the highway and can be diagnosed and maintained at any modern Ford dealership.
