Ok as promised, a diagram for a 6 cylinder Commodore clutch pedal. Please take note of the "hook" area.
And this is the V8 Clutch pedal for a VB-VK Commodore.
I still say Slim, the one in the pics is a 6 cylinder clutch pedal.
Oh i should also point out that Dellow Automotive actually make proper VB-VK V8 Clutch/brake pedal boxes.
