CONCORD, N.C. (AP) — Championship car owners Richard Childress and Rick Hendrick took a few minutes from pre-race preparations for the Coca-Cola 600 on Sunday to smile over their latest achievements: NASCAR Hall of Famers.

Childress and Hendrick, with 25 NASCAR series championships between them, were both part of the latest five-person class of inductees along with drivers Mark Martin and Benny Parsons and pioneering car owner Raymond Park.

Childress and Hendrick had been on the ballot in previous years, but never worried too much about getting in.

Hendrick said he figured he'd have to retire from the sport or die before getting voted into the hall.

"I'm glad we didn't have to retire," Childress joked.

Both owners are still going strong and looking to add to their Hall-of-Fame resumes. Hendrick has won 242 races in NASCAR's top series, including two victories this year by Jimmie Johnson. Hendrick will have Johnson, Dale Earnhardt Jr., Kasey Kahne and Chase Elliott in the field Sunday at Charlotte Motor Speedway.

Childress has won 106 races during his career and will watch Austin Dillon, Paul Menard and Ryan Newman compete here.

The two acknowledged some rocky — and costly — times in their relationship, mostly when Hendrick racer Geoff Bodine tangled with Childress driver Dale Earnhardt.

"We've had some situations where we've had to go up to each other and say, 'We're not driving the cars,'" Hendrick recalled. "It was costing us a lot of money."

The feud and wreckage got so bad in the mid-1980s that both drivers and owners were summoned to NASCAR headquarters in Daytona, Florida, to meet with late leader Bill France Sr.

"I'm not going to use all the words he used, but he said, 'Ain't two monkeys going to mess up our show,'" Hendrick said.

France ordered all involved to go to dinner and straighten things out. "We didn't have any more trouble," Hendrick said.

Childress and Earnhardt won 67 races and six Sprint Cup championships together.

"You look back on that piece of history that was made and to be part of it," Childress said. "It was quite a trip."

The two car owners were initially puzzled by a congratulatory text each received about their Hall of Fame acceptance by NASCAR president Mike Helton just prior to the official announcement. Neither Childress nor Hendrick attended the ceremony at the NASCAR Hall of Fame on Wednesday, in part because of the busy schedule both keep when the Sprint Cup Series is at Charlotte Motor Speedway.

Soon after, Childress said, someone "beat on the door and said, 'You're in the NASCAR Hall of Fame. So I opened a bottle of Childress cabernet and had a drink."

Both owners said they thought about the people who were there at the start and the lean times of learning while building powerhouse race programs.

"How does it get any better than that?" Hendrick said.
