In 1967 the Hoerr team returned to Riverside with the fastback Charger shown below in Riverside's turn #6. The car ran close to the top drivers in practice and qualified 9th. In one of the final practice sessions, something went wrong and Billy Foster hit the turn #9 wall at the end of Riverside's long, long back straight. He didn't survive the crash. Rudy Hoerr continued in USAC for a few more years and had Al Unser Sr, among others, driving his Mopars.
