Need help with body parts interchange

[Dustin]

I have an 01 Sierra 1500 that met a guardrail. I’ve found a decent 00 suburban that has straight fenders, couldn’t find a positive answer in search of whether the fenders are interchangeable. They look the same, but you know how that goes. Anyone know if they’ll work?

They won't work if you're only trying to swap the fenders. Sierra has bigger and rounder headlights than the suburbans/Silverados for that year.
