I just ordered parts from gmpartsdirect.com and already had the part numbers for these parts. (It pays to have two Sevilles.... ) I'm wondering where I can look up the part numbers I need for any other parts I'm looking for?

I had the original part numbers because I had the work on the first car done by the dealer so I just pulled the numbers from the first receipt to use when ordering the part list for the second car.

My one pet peeve about gmpartsdirect.com is the lame "shipping and handling" charges! For crying out loud just price the parts. Never mind the games... sheesh... I really dislike companies that play these games to the point where I avoid them. The S&H game makes me think they are dishonest.
