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.
