     The stock system consists of a riveted-on heat sheetmetal heat
     shield that is faced with asbestos on the gas tank side.  Pantera
     shops sell polished stainless steel covers for this shield which
     slip over the top, and add a measure of reflectivity not to mention
     loads of 'bling'.
     The fellow who restored my car was unaware that this was supposed to
     be a cover, and he accidently discarded the stock shield, leaving
     only the cover to do the job.  I wasn't comfortable with this, so I
     bought some light aircraft engine bay insulation from Aircraft
     Spruce.  This is fireproof, reflects heat, and dampens
     vibration--all good things.  I stuck it to the gas tank side of my
     shield and all has been well since.
     The factory low-performance exhaust manifolds clear the heat shield
     by a fair margin, while the Euro GTS ANSA headers often literally
     touch it, and aftermarket headers are somewhere in between.  The
     tank can be shifted outboard, and the heat shield can follow suit by
     simply drilling out the three rivets which secure it to the chassis
     rail, moving it over and drilling new holes and riveting it again.

     V-8!
