99 Tahoe Bumper Question

[edgein72]

I just bought a 99 Tahoe and being up here in the northeast it has some rust issues. Mainly the rear bumper and the left barn door. I have found a few bumpers on Craigslist but the one thats in the best shape is off a Silverado. I just want to check and see if anyone on here knows if they are interchangeable. They look the same and it would make sense that they would be but i don't want to spend $50, $80, $100 or more and find out it won't fit. Any help would be much appreciated. Thanks folks.
