Hopefully I don't cross the mods by posting this in the wrong area - Started to put this in body work, trim seems like it belongs in body to me, but there is always a lot if interaction here so:
Finally working on assembly on the '64 2-dr Sport Coupe. I'll get some pics up soon. I was trying to install the trunk emblem and it just would not tighten up to the body (one pic shows the gap),with the trim/speed nuts. I pulled it and there were some shavings on the nuts and further inspection showed what is in the pics, the studs are stripped. Now what? Thread the studs and use a regular nut? 3M adhesive? Double back tape? I keep finding missing pieces of trim and other parts and I was able to clean this piece up really nicely, so I really do not want to have to replace it. It looks like the mounting is on rivets that one might be able to drill out to replace the studs, but that also looks like a potential nightmare.
Coupled with that, I noticed that some of the original trim nuts have a somewhat soft, pliable, rubber material in it (kind of like plumbers putty). I think I saw somewhere here someone mentioned "3M Strip Caulk" or something along those lines?
Advice, suggestions, ideas?
Thanks in advance.

I would try running a correct size threading die down each stud to chean out and straighten them up. Follow this up with JB Weld in the areas of the studs missing threads. Finally, run the threading dies down the studs once the Putty has cured.
You're welcome!

Thank you! I will try that this afternoon. I was worried about how soft the material seems to be and trying to thread them down to the point they became so narrow that toothpicks would be thicker. Didn't even think about adding mass first. Appreciate the advice.
Goes back to why I posted the question here.

I tried the JB weld. Let it cure for ~4 hours and then sanded it down to about the same OD as the original studs and tried to thread it with a 1/4-20 die and the JKB weld held, until it didn't. It chipped and broke off on 3 of the 4 studs. On one side and one center stud it seems to have filled the stripped areas and may work. I cleaned and. refilled them all and let them sit overnight with similar results. I sanded everything and recleaned with degreaser and I am going to try one more time. Considering going with more sanding, a larger tap (I ran 5/16"-18 die first and there was no chipping), and maybe some nylon nuts to see if that won't prevent the chipping of the filler. Any thoughts?

Maybe build up thinner layers of the filler, threading each as they cure. Repeat until fixed.

I've been reading this for a few days.
But thought of this possible (rinky dink) fix immediately.
After putting the damaged molding on,
slip a screw anchor on it.
If it doesn't hold tighten a nut till snug,
avoiding too much torque so you don't snap it off.
Otherwise drill those rivets, separate, and fabricate your own fastening system.

possibly drill and tap for cut off 10/24 screws, or whatever size the material thickness will hold. making studs out of them. epoxy them in place.

HOW ABOUT TRYING A THREADED INSERT. cLEAN UP YOUR POSTS AND THREAD ON A LARGER THREAD INSERT WITH LOCKTITE.

Hmmm... that one is interesting. I'll have to see if I can get a size that also fits through the hole in the trunk lid.

At one point I was thinking I might have to pull the riveted in base and do this through the base. It may be the next step. It surprised me how soft the studs on all these original pieces are.

uh, they may not be ribits, they may be posts that are peened over to look like ribits. my next move would probly be making studed plates that i could epoxy on there mix in some shreded fiberglass to make it stonger. not being able to see it and touch it makes this harder to deal with.
happy turkey day

Something i noticed in your picture is it doesn't sit flat to the trunk lid. That could be why your posts stripped out. That pot metal is not very strong. I would try and get it to sit better and then you should put some putty around the posts to seal it from water leaks and rattles and just snug the nuts. You should have to tighten them that much.

Bobb,
Good point. I have been looking around to see if I can find anything out there on the inter webs of someone doing refurb-repair to these, but haven't really found anything. I am thinking these tube nuts might be a viable option, aside from the stripped areas that might not keep it tight to the body. I hear you on not being able to put hands on, makes a big difference. I thought about finding a junk one fro cheap $$ and reverse engineering that one so I don't trash this one.
Keep the ideas flowing. Hope you had a good Thanksgiving.
Cheers,
Scott

I am looking at how the thread inserts might work, but I also wonder if Tube Nuts might work
https://srfast.com/product/barrel-clip-a ssortment-...
The one issue being the stripped, narrowed area not holding tightly. The emblem is away on that pic because I was not able to get the nut to snug down, that is how close that stripped area is to where the nut needs to be to get the emblem flush. Frickin' pot metal. Whose bright idea was it to use pot metal on fasteners? Just dumb.
Hope you had a good Thanksgiving. I am open to ideas. I've been trying to find a process or video on someone refurbing these to see how viable that is.
Cheers,
Scott

I found this and it looks like they may be those mushrooming studs like for the letters that go onto the trunk lid center lip molding.

The more I look at your pictures I'm wondering if the stripped studs unscrew from the frame? If they do I would take one out and try putting a steel thread insert in and then either use a stud or bolt to install it.
