GM Supercharger oil pt# 12345982
Supercharger brng/seal: NSK 1 - 6204.C3 Brng; 1 - 6203.C3 Brng, 1 - 7965 CR Seal
Ok I had a friend with a press, press the shaft out and the bearings off and press the new ones on. I also got the ReoTemp 500 grease for the needle bearings at the back of the rotors ($53 for an ounce delivered- used less than 1/2) good for 100000+ miles.
The seal I took off by drilling 2 small holes in the aluminum 180 degrees from each other, screwed in 2 sheet metal screws and pried it out by going back and forth evenly and it comes out, then press back in with a large socket. THis can be done on the car with the pulley removed and the oill DRAINED.

Sir, you are a genius! Last weekend, I took off the pulley and when I saw the aluminum, figured it can't be done this way and packed it back up. 
To be clear that I have it right: while the */C is on the car, drain the oil and take off the pulley. Drill two holes in the aluminum "cover", put two screws and pry them out. Remove the seal (any special tricks required?), and press a new one back in. Put the aluminum back in (is it going to leak or anything?) and put back the pulley.
If this works, I will be forever indebted to you!
Thanks.

You got it basically.
The seal and aluminum are one piece, so it was tossed. The new seal that I used was also metal, so when I was finished it looked almost the same except my new seal had a mat finish.
I have another seal that is all rubber/neoprene and wouldn't have the metal protection, but does it need it behind the pulley? You could also fashion a shield.
BTW, you do not need to remove the woodruff key.
Good Luck
