From what I know, and I've never had a 126 front sway bar or upper control arm off the car, the sway bar tapers so a shoulder that slips into bushings in the upper control arm. A bolt goed into the shoulder from the front.

I'm not sure what I see in the picture but it looks like the shoulder fell off and the remaining end of the sway bar was pounded to look like a flat mushroom. If that's the case, I doubt it can be repaired in place.

I'll look for the follow-up by DslBnz. I know his car is back on the road without major surgery.
