Any ideas on how this underhood round rubber bumper is affixed to the underside of the hood ? I am reluctant to remove the existing one to inspect not knowing what is behind and if the nut/attachment falls inside the cavity.

Photos and links of what I am trying to achieve are below:

Replacement round rubber bumper is like this - https://www.amazon.com/dp/B075G1K2L5/?tag=wranglerorg-20

Photos of installed and missing are attached:

Just a rubber tit that pushes into the hole. It’s a bit bigger than the hole so you push real hard to compress it, then it expands back out to hold it in place. Here’s a similar rubber bumper but maybe not you exact size

No. There are two elements. Expanding nut that goes in and bump part mounted to it.
You can get it here

or at Lowe's or ACE hardware for $1.
Make sure you get thread matching bolt ,3/4" length

Parts list shows the insert, bumper and screw.

J4005237 NUT, Hex, .19-32x430, Well Type
55176291 BUMPER, Steel Insert
06034205 SCREW, Pan Head, .19-32x.625

.19"-32 is a #10-32 thread. I don't know if the well nut (nutsert) is rubber lined as linked above or just a simple steel/aluminium nutsert. Diameter of the hole would need to be checked against nusert diameter for confirmation.
 
One of the well nuts on mine spins. When the day comes that I dig it out of the hood, I will replace the rubber well nut with a metal nutsert.

I just did that yesterday.Ace hardware rubber expanding nutsert is 10-32 thread.Lowe's is 10-24 thread.OD 1/4" or so. 3/4" bolts is required length. Metal nutsert is probably not the best choice on a hood that will vibrate and shake.I assume that 's why they used what they used.
