They changed the grille and taillight to the 1968 model, and then painted both cars identically. They sent the legal weight car through the technical inspection with the number 15 and again with the number 16 on it. Then they put both cars in the race, number 15 and 16, one car being 250 pounds lighter. They won the race, finished third overall, and went on to win 10 out of 13 races that year. They also acid-dipped the body on the Camaro and had to caution people not to lean against it, for fear it would dent. The lightweight car was featured on an episode of Dream Car Garage on Speed TV in 2005. In 1970 new Javelin team owner Roger Penske and driver Mark Donohue would breathe new life into the AMC team.

Indianapolis 500 In 1969, Penske and Donohue raced in their first Indianapolis 500, with Donohue finishing seventh, winning the rookie of the year award. Donohue raced at Indianapolis each year following, finishing second in 1970 and 25th in 1971. Donohue won in 1972, driving for Penske. He finished the race in his McLaren-Offy setting a record speed of over , which stood for twelve years. The victory was the first for Penske in the Indy 500. NASCAR Donohue raced in several NASCAR Grand American races and a NASCAR pony car division from 1968 until 1971. In the 1972–1973 season, driving an AMC Matador for Penske Racing in NASCAR's top division, the Winston Cup Series, Donohue won the season-opening event at Riverside. That race was Penske's first NASCAR win in a long history of NASCAR participation.
