Dillon set his career best start of 4th at Richmond, and also led 21 laps at Gateway before a late crash.
In 2000, Dillon moved back to Richard Childress Racing (RCR), driving the newly formed #21 Rockwell Automation Chevrolet.
Dillon did not improve that much, as he did not qualify for the season ending race at Miami, and his best finishes were a pair of top-10s.
Dillon's driving career ended in 2001 after getting injured in a wreck at Bristol Motor Speedway.
The following was a quote from RCR: "Richard Childress Racing (RCR) named Mike Skinner as the driver for its BGN #21 Rockwell Automation team this weekend at Texas while fulltime driver Mike Dillon recuperates from injuries sustained from a March 24 crash at Bristol.
"Mike (Dillon) took a hard lick at Bristol so he's pretty sore and stiff," said Richard Childress, president and CEO of Richard Childress Racing Enterprises, Inc. "He also took a hard lick a couple of weeks ago testing in Nashville.
Mike Dillon currently serves as the General Manager of Richard Childress Racing's three NASCAR Cup teams.
Beginning in 2007, Dillon was the spotter for the Richard Childress owned #33, then driven by Clint Bowyer.
Dillon made three career starts in the Craftsman Truck Series, all for Richard Childress.
In 1997, Dillon made his debut at Phoenix driving the #33 Realtree Chevy, where he started 29th and finished 26th.
