Supercharger woes

My Supercharger has been making this rocks/grinding noise from the throttle body area. I replaced the front plastic coupler and unfortunately that didn't solve much. So I thought maybe the needle bearings. I did some research on the forum and realized I can't change the needle bearings without a press of some sort and drilling and tapping, so I decided to buy another used low miles supercharger that came of a 97 park avenue. Will this supercharger work for my car? Is there a easier way to fix my current supercharger instead of spending way more money? Another problem I ran into was that while I removed the supercharger I tore the gasket and its stuck in pieces on the plenum. How do I get this off? I tried a razor blade but I don't want to score and scratch it... It's driving me crazy!!

Any help is appreciated. Thanks

A 97 M90 will not fit a 95 M62 if I remember correctly. As far as cleaning the old gasket, there is a special tool for cleaning aluminum. A rubbery small disk with little rubber fingers as not to scratch OR leave debris.

Thanks for the replies guys. It is very appreciated. I tried looking for those rubber disks for cleaning aluminum but no one seems to know what I'm talking about. Is there a name for them?

They are MMM Roloc abrasive brushes. You will need a air drill or die grinder and the Roloc adapter.

How much is a used supercharger? brand new they are like 2 grand it seems, but my friend tells me I can grab one for $75 out of a junkyard. this seems impossible someone would sell something that cheap

At a local junkyard i saw an m62 in a 95 riv. I asked a price just out of curiosity and he said $175.

There are many rebuilt units on E-Bay for varying prices. If you aren't comfortable with repairing your own this may be the way to go.
