I have an old, rusted 89 aries with unibody construction. The car is
dead because there is no fule pressure. I suspect the fuel pump. To get
to the fule pump, I had to drop the tank which means I had to undo the
nuts holding the gas tank mounting straps.

When I attempted to undo the nuts for the gas tank mounting straps,
they both broke.

The nuts were on a threaded rod that seems to have been welded to the
unibody.

So what to do now?

I figure the best solution is to drill near the broken stud and and if
possible thread the hole. Then thread a threaded rod into the hole and
place nuts on both sides too secure the threaded rod. Use locktite so
they won't come undone. This will then once again give a threaded rod
to mount too.

I think this is a solution. Does anyone have a better solution?

How would a professional handle the situation? Would the weld a nut to
the unibody?

thanks!
