I will take a picture of the pedals in my car. I don't understand why it doesn't work with your car, it is supposed to be quite simple, are your the pedals in your car much different according to other cars? I fitted them just on top of the existing rubber pads, that worked out best for me.
I would love to help, unfortunately there's only a rather large pond between us... I'll send you a PM with the pics.
So, good luck with it and take it easy.
