On December 21, 1967, Chrysler Corporation announced Darel Dieringer would be paired with Mario Rossi to run a partial schedule for 1968. In Rossi's #22 Plymouth, the pair competed in eighteen 1968 races as well as a race at Middle Georgia Raceway in November 1968 that was the 1st race of the 1969 season.
After parting ways following 1968, Dieringer all but retired from GN racing. He didn't race again until 1975 when he returned for 4 races. Rossi then brought in Bobby Allison to drive for his team in 1969-70.
