The car Rusty is driving in this photo is an Impala, if you pay real close attention the area under the headlights is where the parking/turn signal lights would be on a stock Impala, on Rusty's they have been removed and replaced with sheetmetal, as the Impala did not have the wrap around side marker lights.
As in this bottom photo this is a Caprice, Impala's as the above don't have the wrap around side marker lights...
