Yes
Yes it is the same.
Will a 2000 chevy 2500 bumper fit a 2005 chevy 2500
Yes they are the same
No it will not fit. You would have to use the 2006 fenders, grille and Headlight assembly to fit the bumper.
It should, but the upper bumper pad on the 2500 may be thicker, they both bolt on the same way though, measure the height.
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.
yes it should.
No totally different style
No
it should. the only thing is if one was a diesel. sometimes they have a spacer on the diesel models.
YES, That would be a direct swop.
Nope i dont think so you would probably need to some major bodywork if you want it to fit
