AU for Seton and bessy, hybrid for Lowndes
From prodrives website.
"The three car team will initially run two 2002 specification Ford Falcon’s driven by Glenn Seton and David Besnard and a new 2003 car with mechanicals from the previous car, driven by Craig Lowndes. Prodrive will develop an all-new car based on the Ford Falcon BA during this season and is constructing a new facility to house the team next to FPV in Melbourne, which will be ready for the 2004 season."
SO Seton and Bessy get AUs and CL gets AU with BA skin, or BA with AU engine and mechanicals, or something.
The AUs are possibly GSRs old cars?
