95 Riveria needs turbocharger

I have a 95 supercharged Riveria and the supercharger is knocking; she has no power. Can driver her but at idle she rattles. Thinking about replacing the supercharger but can't find and procedures (tourgue, steps...etc). Is it worth it?

I her day she was something; has all the bells and whistles. Had a cell phone but it is gone now. Body is straight but paint needs some help. Any help?

Just go to a junk yard and pick up a used S/C. Go online and do a search for ,GM repair manuals,or go to Helm.com and buy a manual for your year. On the 95 its a piece of cake to swap out a S/C. its also a piece of cake to swap out a bad coupler. do a search ,here,for S/C couplers. The Riv is surprisingly easy to work on mechanically speaking.the electronics are though, require knowledge
