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

[Rob Dumoulin]

I did not think that the glass was adding structural integrity, but instead
thought somehow that the car being on stands two weeks, which may have been
closer to three weeks, tweaked the opening just enough that it the glass
were a little off it might have been snug on install then cracked during
driving.

I did not inspect the glass prior to install and was not able to be there
when it was done, but my glass guy is a stand up talented guy and will redo
it for free. I plan to pass any advice from you guys to him.

You are correct that the 5 point harness bar is installed, and it was not
installed when the first glass was put in. However, the bar is a perfect
fit and has no extra pressure added to make the bolts thread. If anything,
I would think it would add support.

   I did not think that the glass was adding structural integrity, but
   instead thought somehow that the car being on stands two weeks, which
   may have been closer to three weeks, tweaked the opening just enough
   that it the glass were a little off it might have been snug on install
   then cracked during driving.

   I did not inspect the glass prior to install and was not able to be
   there when it was done, but my glass guy is a stand up talented guy and
   will redo it for free. I plan to pass any advice from you guys to him.

   You are correct that the 5 point harness bar is installed, and it was
   not installed when the first glass was put in. However, the bar is a
   perfect fit and has no extra pressure added to make the bolts thread.

   Rob what is probably nagging your subconsciousness is the idea that the
   rear glass is a part vital to the structural integrity of the car, and
   without it being in place the shape will change during jacking.
   I'm no engineer but that idea sounds absurd and you should eliminate it
   from your trouble shooting thought process.
   Sure they flex some, but rather the idea of an imperfection in the
   seating like Mike D. said sounds more plausible.
   Is the opening entirely straight sitting on the ground? Is there
   extreme heat near the suspect cracked areas? Was the glass properly
   de-burred of all sharp edges? Do you have a seat belt bar mounted to
   the firewall that might be preloading it?
   Just shots in the dark.A
   Best of luck,
