What is this?

[TahoeRestore]

My son just bought a 2001 Tahoe 5.3 with 115K. It's been garage kept for 17 years by a seasonal resident of Florida and great shape cosmetically. We were doing some preventative maintenance and removed the plastic rear belly pan (dog bone shaped?) this was on the top and fell out. Does anyone recognize where it may have come from? He will be joining the forum soon.

if it came out of the inside it could be the remnants of the factory sub woofer if it had one, drivers side rear panel with the "grill holes in the plastic"
