[DeTomaso] Rear Window Cracked.....again

[Asa Jay Laughton]

If possible, perhaps check all the weldments on the firewall, paying special attention to the engine access framework.  It sounds to me like that area may be flexing for some reason.  Note, I'm not an expert by any means, it just seems that something is allowing that area to flex and crack the window.

   If possible, perhaps check all the weldments on the firewall, paying

   that area may be flexing for some reason.  Note, I'm not an expert by

   When I got 1488 eight years ago, the back window was cracked from right
   above where the driver side seat belt mount bolt goes through the back
   trim
   panel to the roof line. This was a single crack with no side  "spider"
   cracks deviating from it.  I have no theories of how the glass was
   cracked
   before I purchased the car.
   During the restoration, I bought a new gasket and had a piece of
   automotive
   glass cut using the original as a template and installed by a friend
   who is
   in the glass business. The car has an adjustable rear cross member
   brace
   installed over the ZF as many of us have and the car was sitting on
   jack
   stands with the wheels off for 2 weeks prior to the wheels being
   reinstalled and taken off the stands to put the new windshield and back
   glass in.
   The car has been drive on one long trip (to SE Pantera Prez Tim
   Clinger's
   house), a few docile cruises, and a few sporty ones since the install.
   No
   major driving events and only a few time in the 90-100 MPH range.
   The new back glass cracked again but this time it cracked more inboard
   from
   the first crack. The new crack starts just above the driver side frame
   rail
   and has 5 "spider" cracks fanning out from the bottom point of origin
   to
   the top.
   My glass guy says he may have made the fit too tight and will replace
   it no
   charge. I'm looking for any other theories that could explain it before
   I
   put another one in and it breaks again.  Is it possible that the car
   being
   on jack stands could have tweaked the car enough to cause the glass to
   bind
   as it re-tweaked to its natural state?
      When I got 1488 eight years ago, the back window was cracked from
   right
      above where the driver side seat belt mount bolt goes through the
   back
      trim panel to the roof line. This was a single crack with no side
      A "spider" cracks deviating from it.A  I have no theories of how the
      glass was cracked before I purchased the car.
      During the restoration, I bought a new gasket and had a piece of
      automotive glass cut using the original as a template and installed
   by
      a friend who is in the glass business. The car has an adjustable
   rear
      cross member brace installed over the ZF as many of us have and the
   car
      was sitting on jack stands with the wheels off for 2 weeks prior to
   the
      wheels being reinstalled and taken off the stands to put the new
      windshield and back glass in.

   that
      the car being on jack stands could have tweaked the car enough to
   cause
      the glass to bind as it re-tweaked to its natural state?
