I currently have a 2000 grand prix daytona 500 edition and the transmission is just about to take its last breath at a moment's notice. So tomorrow I will be getting a 2002 grand prix se 4dr sedan and I was wondering if the trunk and hood from the 2000 would fit on the 2002? I would assume they would being in the generation. And I was also wondering if the 2000 roof rails would fit on the 2002? Being the 2002 is longer because of the 2 extra doors not sure if it does. And lastly are there any interchangable parts (other than the engine parts) that would fit the 2002? Eg.... water pump, radiator, power steering pump, etc....

Any information is useful please and thank you
