When is a SAAB Viggen not a Viggen?

[chaos4NH]

Just curious, I see SAAB Viggens ran in SSB and SSA at Lime Rock. Rules say SSA. Was this a mistake by the driver (s) who entered their Viggens in SSB? That is supported by the Viggen which ran in ST2 - a correct move from SSA. As I see no class changes in the works for 2008, I am bringing it to the attention of the drivers to classify their cars correctly.
