Who has a known A66 '70 Challenger equipped with the 15" wheels/tires?

Is there a spacer between the lower control arm & bumper? Maybe, tire rub was the reason the E60x15s came & went?

Maybe 340 cars didn't need them, unlike the "heavy-nosed" big blocks? Do T/As have them?

B18 LA car - I thought 15" wheels would be appropriate for this car, but it is after E60x15s were no longer STANDARD?
