Cheaper firewall fix?

[Max Wellhouse]

I finally tracked down the guy out west that makes that $100 steel 
gizmo that prevents the firewall from collapsing/flexing so the 
clutch pedal works properly.  The  VW QSW folks also have the same 
problem.  I was wondering if any of you had a less expensive or 
better repair without any welding involved.  My 4kq is flexing and I 
don't need it to break the wall or crack somewhere.  Pardon the 
jargon, but I'm posting this to both lists.

Thanks
