Was replacing the front sway bar links yesterday, as they were rather noisy. Took the front bar off the car, pulled the old links off, pushed the new ones on, easy-peasy. Go to bolt the bar back onto the car, and one of the little mount bolts snaps off as I'm tightening it.

It broke flush with the body.


So now the front sway bar is being held to the body with only 3 bolts instead of 4.
Took it for a drive, the knocking noises indicative of worn links is gone, nice and smooth sounding over small bumps. Took some faster turns and didn't hear any noises there either, so I think it's secure enough.
What would you do? Remove the sway bar again and try to drill out the broken bolt? Or just drive it? I'm leaning towards the latter.
