Hello Everyone. I have a 1999 Grand Prix GTP with the supercharged 3800 engine. The car is completely stock and I'm content to keep it that way for now. However, I did suffer a problem today. The supercharger belt tore. I thought nothing of it and purchased another. However, upon my attempt to install it, I found the grooved pulley under the spark wire distribution box (that is a guess for this component) is completely gone with the exception of its hub. First, what is the correct name for this part and perhaps even a GM part number. Second, how is it replaced if it can be? Thank you everyone for your input.
