Body Parts interchangeability between Silverado/Suburban/Tahoe, etc.

Hello All, does anybody know if there is a list anywhere of Body Parts interchangeability(not sure if this is a word) between Silverado/Suburban/Tahoe, etc.  and the Avalanche?
My otherwise cosmetically OK 04 Avalanche(non cladded) has develop rust on the front bumper, and I would like to replace it but on a budget. I would think there are some parts at LMC, or junk yards from other model GM vehicles that might fit, but haven't been able to find a list anywhere.
Any thoughts?
Thanks.

Since you have the WBH Avalanche...any bumper from a 03-06 Silverado should work.

Thanks, are there other parts that are interchangeable between them?

Most of the components from the B-pillars (between front and rear seats) and forwards are compatible between 03-06 Avalanche and 03-06 Silverado.

Headlights, hood, dashboard, etc...
