I have a 04 Silverado LS 4.8

Vehicle was involved in passenger side crash- Still driveable, drives straight but needs the following.

Quarter panel- paseengerside
Radiator support brackets- Top, Bottom, Hood support
Passenger side head light bracket

I have all these in hand BUT

I need assistance in locating a parts diagram for the front body,frame.

List of nuts, washers, bolts, spacers, etc
Diagram of how everything goes back together

Can anyone please help me or direct me to the right place- I asked my local dealer and was told they don't give that information out- I could order the parts from them but no illistrations, etc

Thank You,
