Sway bar bushing bolt busted off in the frame. Want to discuss options.

While undoing the sway bar bolts, one of the internal nuts broke lose from the welds. Ended up having to cut it off as the bolt/nut just spun and spun.

So, wanting to keep my sway bar, I see my options as:

a) tighten up the front bolt and weld the rear to the frame.
b) enlarge the round hole right above where the broken nut is and replace the nut/ tighten though the hole.

What do you guys think?

 

For anyone interested I have fixed a few of these broken loose nuts.

I first drill out the holes to be able to fit a weld nut of M8x1.25 then make a small plate of 1/8" or 3/16" what ever I have handy.

After welding the weld nut to the plate the plate is welded to the frame. Nuts being up into the frame. I always use new bolts.

It works good for another 20 years .

I always never seize the bolts.
