Grinding, rubbing, whirring noise coming from transmission after replacing clutch

As the title says, I am getting a grinding noise coming from the transmission area after I replaced the clutch, flywheel, rear main seal, and axle seals. It has gotten progressivily worse and isnt tied to the Engine because it varies by car speed not engine RPM. Also the noise gets worse when turning. Does that sound like diffrential bearing, CV axles, or wheel bearings? Also since I will probably need a new transmission, there is a 2003 MSP with a blown engine on Craigslist. Could I buy the car then swap the newer trans and the entire ABS system into my car that doesn't have ABS?
 
I found out that the grinding noise was my rear parking brake rotors. Just FYI to anybody who is looking for a possible solution
 
As far as the MSP goes, you would be better off buying it and swapping the motor from the P5 or finding a motor for that car instead. Do you have a link to the for sale ad?
