Need GM part no. for driver's side window

[jaslo]

Does anybody know where I can find the part no. for the driver's side window and good place to buy the power window assembly. Its for a 2001 chevy silverado, and I don't want to buy aftermarket because it might not last as long.

If you don't want aftermarket then you will need to go through the dealer and possibly a place like rockauto.com. Rockauto tends to have OEM options.
