Yes. Only if you have 6 lug pattern. All Chevy trucks 6 lug patterns are the same 6x139.
Im not sure it all depends on the bolt pattern. The bolt pattern depends on what axle the truck has and stuff like that. I doubt the bolt pattern is the same.
No everything about it is different.
Um... I would sure hope so since they are both 2003. But if you mean "will a bumper from a 03 silverado 1500 fit a 03 silverado 2500, (or the other way around)" I am not sure. It might, but the frame on the 2500 is bigger than that on a 1500.
The 2003 is the 1st generation Silverado and the 2007 is the 2nd generation Silverado. So it is unlikely the hoods are exactly the same but I would not rule that out 100%. Any salvage yard can answer your question 100%.No.
It is around 345 hp at the crank and 20% drivetrain loss because of the 4wd so about 300 at the wheels.
