yes, John
you'll still need to bend your pedals even with more reason on the MKIII because of the smaller footbox. and the throttle pedal arm will also need to be shorten.
The newer pedal boxes (on the MKIII) require to be trimmed in a couple of places to allow the throttle cable to clear it and for mounting it flush with the mounting plate.
if you are going to use the cruise control from your donor you will also need to move the clutch de-activation Cruise Control Switch, add a longer clutch stop tab, etc.
It was easier for me to bend them with an acetylene torch....
