Sway bar stud failure survey

[tom shewchuk]

Sway bar studs for 1966 to 1988 sway bar studs are becoming hard to get. Mine snapped and, I can have some made, but I' wondering about the failure rate of this part. #11 in the diagram. Just wondering if it's worth my while to make a bunch of them.

I have one on which the upper threads are stripped. Since it's 25% of what holds the spring in place, I would like to get it replaced.

Never heard nor seen one brake. Maybe you're the first?
