Would anyone know?. Will the floor pan, for a replacement carpet, be the same in all E23's. Could there have been a different Trans. tunnel shape for a specific model? I know there may be a difference because of the dead pedal in some models.
I don't know for certain, but am 99% sure that they are the same. There are quite a few transmission swapped E23's out there and none that I know of required any change to the floor pan.
