Simply cut/grind the broken/corroded stud away clean/prep the area, and glue on a new one...I wish I'd known of this two years ago when I was doing all that cutting and welding...
Leading evidence: 'Use coated' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Clean /prep the area, and glue' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

U have to weld a new in or i drilled it out and used a push in "christmas" tree plug.

I wound up using a self taper and barely started the treads then welded it to the chassis.

A $50 experiment ($20 and change for 10 studs, $18 for the adhesive, the rest for tax + shipping).
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

When I change oil on my cars, I have the opportunity to get a look at the condition of everything underneath that typically are ignored until they become a problem.

I have the same problem a lot of mine are heavily corroded and I was struggling to get the bits to tighten, I found buying new nuts helps getting it to bite on a worn stud but if it's missing I don't know !
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I noticed a stud is missing for one of the plastic nuts that should be holding up my underbody panel, but these appear nowhere in the parts catalog. All I can find is the plastic nut is T5. Anybody have any ideas?
Unfortunately as De Jeeper points out, these are welded to the body and not easily replaced. Once they are gone only alternatives as noted by De Jeeper are the fix.
I'm fortunate to have a lift in my garage. When I change oil on my cars, I have the opportunity to get a look at the condition of everything underneath that typically are ignored until they become a problem.
Maybe 10 years ago, I became aware of FluidFilm. I hit any fasteners showing any sign of corrosion with a little spray and made this my routine. I hit anything I feel should need some protection. The best feature of FluidFilm is it is lanolin based and will not break down paint ,plastic or rubber.
Protection and prevention has worked for me.
My .02 cents.

I was able to find �weld on� copper coated zinc studs. They have a standard fine thread though, unlike the stock studs that have a wide sheet metal like thread. For this I just use a fine threaded tap (I don�t remember what size off hand) and tap the plastic nuts so they thread onto the stud. The studs are actually made for a �stud welder� so they�re not easy to attach with a wire feed - but I have gotten a few to work...
I have the same problem a lot of mine are heavily corroded and I was struggling to get the bits to tighten, I found buying new nuts helps getting it to bite on a worn stud but if it's missing I don't know ! Be great if someone chimes in with an idea like a stud that can be bonded onto the underbody or something that can be adapted with epoxy resin or similar?
Another idea, would be a "nut-sert"... You drill a hole and insert it like a rivet, but it's got a female threaded body that you can attach a screw to (regular machine thread SAE or Metric are available). I've got one of these tools - it doesn't work everywhere but when you have clear access they're great. See here...

Yes...I love nutserts! They work great when done right. I'd use the smallest one that would get the job done. Keep the drill shallow as possible to make the hole to receive it. (you don't know whats on the other side of the floorpan). I'd also coat them a bit with RTV or another sealer to help with corrosion between the nutsert and floorpan before crushing them tight. After that keep the fasteners used coated with something to protect from further corrosion. Good call dporto.
^^^ Yes, Eastwood makes a aerosol internal frame coating that would work great to spray through the holes you drill...

Here we go! And... it's in America (I tried to order from the UK site with no luck - seems they only ship in UK...Brexit? Hmmmmm

^^ And no drilling holes in your chassis - this seems like the way to go. Simply cut/grind the broken/corroded stud away clean/prep the area, and glue on a new one...I wish I'd known of this two years ago when I was doing all that cutting and welding...
I did. A $50 experiment ($20 and change for 10 studs, $18 for the adhesive, the rest for tax + shipping). I know I've got at least 4 or 5 studs that the plastic nuts don't like to stay on, so I figure in the long run it'll be worthwhile to do 'em...
I just got the smallest size, & I'll tap the nuts to fit the studs. The choices are kind of limited...More available in much larger sizes - it looks like these things are usually used in Marine construction. Autoatlanta has the nuts listed as "T5" if that helps...

I just finished up about a dozen of these because of my mezger swap. I wound up using a self taper and barely started the treads then welded it to the chassis. Finished it off by cutting off the head. The course threads hold the plastic retainers well.
