Rear windows failed NASCAR inspection
The cars will be held indefinitely and taken to NASCAR's research and development facility in Concord, N.C., for study, NASCAR spokesman Mike Zizzo said.
The preliminary inspection was for the Nextel Cup race at Bristol Motor Speedway.
The rear window of McMurray's No. 42 Dodge failed to meet the corner-to-corner measurements, while the roof on Foyt's No. 14 Dodge did not meet specifications, Zizzo said.
Andy Graves, team manager for Chip Ganassi Racing, said the window on McMurray's Dodge was about 3 inches too big and the team had no immediate explanation for the mistake.
McMurray's backup car, which has never been on track, passed the initial inspection and the driver was permitted to take part in Friday's practice and qualifying.
Foyt's A.J. Foyt Racing team had to withdraw because his only backup car was set up for superspeedways and could not be used on the half-mile Bristol oval.
NASCAR impounded one of Tony Stewart's No. 20 Chevrolets last March and eventually returned everything but the body of the car to Joe Gibbs Racing.
The Chevrolet entered by Hendrick Motorsports for rookie Kyle Busch at Homestead last November also was confiscated because of its rear window.
