[V8] Subject: Re: Subframe bolt. Stripped hidden bolts

[Pat Martin]

There is an S6 in my shop with exactly this problem.  The decided solution
was to drill a large enough hole in the body to get the broken loose not so
captive nut out and weld a nut onto a 3"x3" metal plate that was then welded
into position on the frame rail.  A corresponding plate with just a hole in
it was welded onto the other side to match the change in height.  This car
was getting delrin subframe bushings in it so the bushing were machined down
to compensate for the additional height.  I personally think this step was
unneeded as the geometry change was minimal at best but it was easy enough
to do so...  

If the nut is still captive but simply stripped than certainly trying to tap
it out with a larger bolt would be easy enough to try.  I might require the
use of a machined bushing however to compensate for the additional bolt
size.

Not an option in my case, since the captive nut was not so captive, it
was loose in the "cage" and it was too tight a fit to get anything in
there to hold it in place.  The nut would only stay put counterclockwise
(luckily.)  

The helicoil might work well for Louis's problem, I think his is only
stripped.

What Veedub repair is this?  Stripped seat mounting bolts?
