Just bought a spare alternator for the EB1. It is a Bosch with a wide ribbed belt. I have a narrow ribbed belt on the car. I thought that there was a v belt on earlier models and then there was the ribbed belt. Now it seems that there must be two different ribbed belts for EB. Ive been told that I can use the wide pulley with the narrow belt, and that it aligns. Is this correct? It would seem that if I replace the pulley for a narrow one, there may not be enough thread to seat the pulley. Can anyone help me with a bit of info here?
