Rear bumper advice????
 

So I'm replacing a rear bumper on a 1998 tahoe, any of you chevyheads know if a bumper bolts up from any other year tahoe, other chevy, or gmc??please be 100% don't just post some maybe or I think ****..thanks.

Anyone have the bolt dimensions to fit a 2004 Z71 Tahoe rear bumper, or know where to find them? My daughter bought a replacement bumper that did not come with the mounting hardware. She needs the mounts and mounting hardware to go with the new bumper. Seems like all the pieces I can find indicate they will not fit the Z71 Tahoe. Any suggestions? Thanks.
