'99-06 GM rear bumper interchangeability - dually?

[olsen_karl]

Anyone know if the SRW and DRW rear bumpers are interchangeable on GMC Sierra/ Chevy Silverado trucks in the 1999-2006 body style?

I have a fairly rusty rear bumper on my SRW 3/4-ton, and found a "like new" one on craigslist, but from a DRW 1-ton. From google, it looks like it should bolt right up (can't find any different part numbers for SRW/DRW), but I'm not sure.

AFAIK they are the same. The only bumpers that I have seen that are different are aftermarket dually bumpers, other than that all of the manufacturers use the same rear bumper whether it's SRW or DRW.
