guy crashed my 04 Sierra (need help)

[VroomVroom]

This is testing my memory a bit, but both should work just fine. (As long as the 2000 isn't a Denali model, which is still the GMT400 design.) The only potential issue that comes to mind is in ideally matching the front suspension - i.e. coils in 2wd models vs torsion bars in 4wd ones. I can't recall if that will actually matter, but it might be worth considering.

Good luck - sorry to hear about this. '04 was a great year on the -800 platform.
