So I swear the convertible top frame in my '99 cab is made of metal that disintegrates over time. Hard to fathom where Porsche found such a material. Anyway, there was some rattling from the top near the "hook" at the front. Turns out that two of the four screws holding the hook mechanism to the top frame had fallen out. One of the threaded holes was 95% stripped (a bit of bite remaining) while the other seemed to be OK. My solution was to put blue Locktite on all four fasteners and tighten them down securely but not enough to strip them more. I'm currently waiting 24 hours to give the Loctite time to cure. Hopefully this will solve the problem for a while anyway. Any other ideas for solutions? I guess I could try rethreading the holes to fit a larger sized screw. The thing is the metal seems kind of brittle.

Coverage and how to read this overview
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.

Is making new threads and a slighter thicker bolt an option? Since mine is a cab, I'd be interested in pictures if you have any.
If it holds any weight I wouldn't do anything like that, it'd just pull out. I'd either try to step up to a bigger bolt, or put a heli-coil in. But, that's without seeing it and without knowing how much room there is to drill and tap the hole without hitting the canvas top.

Here is a pic of the mechanism (thanks Pelican). I dont have a pic of the holes with the screws out (and the mechanism off). The arrows are pointing to fasteners in question. Not sure if a nutsert will have room on the back side to crimp on to or not.

That is the one I was trying to send you to. There is another one that shows extracting the broken pieces of the brass nut plate from the header.
