[QUOTE="THunterW, post: 13719546, member: 149912"] After reading numerous similar issues with other 99-04 Mustang owners snapping or breaking their hood studs the way I did, I decided to tackle the issue and try to repair my broken bottom passenger hood stud. There were a lot of threads on different forums where people thought the stud is welded to a backing plate that is attached to the inner layer of the hood with a single rivet. That is not the case, as the stud is actually pressed in to the backing plate. My stud did not snap in half, but had actually rounded itself out of the hole it was pressed into causing it to freely spin. Since the stud was spinning freely in my hood and the nut was completely seized onto the stud also, I had to cut the stud to remove my hood. [ATTACH=full]529892[/ATTACH] Excuse the mess... [ATTACH=full]529893[/ATTACH] I began to use a Micro Grabbit screw/bolt extractor since I was expecting the stud to be welded to the plate, but the stud ended up falling into the hood and luckily I was able to retrieve it. [ATTACH=full]529894[/ATTACH] [ATTACH=full]529895[/ATTACH] [ATTACH=full]529896[/ATTACH] [ATTACH=full]529897[/ATTACH] And this is what the back of these studs looks like. Notice on the underside of the cap there is that star shaped thing, well that's what's supposed to keep these studs from rotating on you when they are pressed onto the mount backing plate. The nut was so seized on this stud that it caused it the stud to round itself out from the mount plate. [ATTACH=full]529898[/ATTACH] Stud halves next to each other. Was using vice grips to try and get the nut off but it wouldn't budge. [ATTACH=full]529899[/ATTACH] [ATTACH=full]529900[/ATTACH] What the stud would look like complete, about 25mm in length or almost 1". [ATTACH=full]529901[/ATTACH] [ATTACH=full]529902[/ATTACH] [ATTACH=full]529903[/ATTACH] The stud is actually solid and not hollow, the hole is from where I began to drill it out when it just fell into the hood. My original intentions were to remove the stud and tap the mount plate for another M6 x 1.00 stud or bolt, but the plate was enlarged too much to tap it so the only option I saw left was to install a bolt and epoxy/JB Weld it into the hood. I decided to use a M6 x 1.00 25mm length cap head bolt that I got at Lowes, and JB Weld it into the hole. [ATTACH=full]529904[/ATTACH] [ATTACH=full]529905[/ATTACH] For the head of this bolt to fit into the hole, I had to enlarge it with my drill, ending on a 3/8 drill bit. This was large enough for the cap to fit snug inside the hole. [ATTACH=full]529906[/ATTACH] [ATTACH=full]529907[/ATTACH] I picked up this Loctite epoxy weld kit and dipped the cap of the bolt into the mixture and placed it into the hole. I adjusted the angle of the bolt to match the upper factory stud so it will mount correctly. I also applied the compound around the bolt on the outside of the hood for extra support. I'm going to let the compound cure for at least 24 hours then will sand it down and paint the remaining amount with touch up paint to have a factory look.

I checked the compound this morning after I let it sit overnight for 7 hours, and it had a soft texture to it. First time I've ever used this Loctite kit, but I assumed it would be hard like actual JB Weld. This stuff resembles B 1/2 sealant that we use on the edges of aircraft panels.
