My blower is losing its breath...
The SC is my riviera seems to be ****ting the bed as of late, at 132k its got a bunch of age on it, and with 35k miles of those driven by me its been taking it like a champ until recently... so has anyone ever rebuilt or replaced an m90 on a 3800 car?

Used to work with a GM service manager, said they had bins behind the shop full of them!! They really only come already built, not much out there to rebuild them with. Check ZZPerformance, Intense-Racing.com. Also try 3800Pro.com or FullthrottleV6.com, someone can point you in the right direction, you don't want to get one off eBay using Chinese bearing assemblies.

When I had to get mine done I was in school and didn't have the time to do the repair.
The ONLY way the M90 was available from GM was as a complete assembly, which was $2500 or something crazy like that. At the time bearing and coupler kits were not available so I got that remanu unit which was of very good quality.

Does it make noise? How is your belt/tensioner? If you pull the belt and turn the pulley, does it clunk or grind? If you replace the coupler make sure you use a stock one and not an aftermarket.

I have an S/C with a modular pulley if you need it, $125 takes it since I'm sick of looking at it. Good coupler, bolt on and go.
