Hi Bruce,
The thread for the anti roll bar brackets is in a "weldnut" which is
installed on the inside of the frame. If you could get a helicoil in it
would probably hold fine as the loads on the bolt are not really that high
however, in my experience, the 3 little spot welds which hold the weldnut in
place will usually break free as you try to run the helicoil tap into it.
I usually end up cutting the entire rectangular plate out of the frame and
installing a new one with a 1/4" thick 1" x3"  drilled and tapped thread
plate welded inside it after which you have to repaint the area etc etc....

OK, I would like some thoughts and/or other opinions as to a solution to 
this problem.  While replacing the anti-sway bar bushings, I discovered that

the rear bolt on the left side frame bushing strap was backed out of its 
hole about half way.  I then discovered that the threads on the bolt were 
rounded off.  I retapped the hole (5/16 24) and proceeded to bolt it all 
back up (new bolt, of course) when, just as that back bolt was about 
snug--ZIP--out it popped.  I ran the tap up the hole again, but 5/16 is not 
going to hold.  So, I can see two options: (a) drill out 21/64 and re-tap 
using 3/8 24, or (b) drill up through the top of the frame rail, and use a 
long bolt w/ a fender washer and nut.  Thoughts?  Other options?  Given the 
stresses on the bolt, I'm reluctant to use a heli-coil.
