is there any differences between Rover Mini Pedal Boxes between boosted and non boosted cars ?

I know the boosted cars have a linkage from the pedal to the master but is there any differences with the pedal assembly itself ?

The pedals have a slightly different shape and are a bit thicker, the pivot pin size is bigger in the booster version too (7/16 instead of 5/8 but dont quote me on it).
The framing of the pedal box is much the same except the later ones have the bracket for the electric brake light switch and some a bracket for an OBD plug.
The return spring is different too.
