Supercharger

Is it hard to remove and replace a supercharger in my 92' Bonneville SSEI, I am mechanically inclined but unsure of superchargers. Also, I am looking for a new or preferably rebuilt Supercharger unsure where to find one other then ebay. I have no luck on ebay so far. Any ideas are appreciatted.

I just put one on my car last month. Email me, and I can give you the details. :)
