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

Trim the glass (Pattern) an addition 1/16th of an inch all around. That is
what an old time Pantera guy told me what to do when I had to replace the
glass... That worked perfect.

If you are cracking the glass ... it's obviously stressed... and it's
pushing to hard on the rubber.   Like mentioned before, float the glass.

Enjoy,
