I heard a rumor that some outfit was reproducing the rear glass for
65/66, I wonder if the same hold true for a 67.....  Also, i seem to
recall a couple of ads in one of the magazine I get advertising hard
to find glass. I'll take a look and see if I can find the ads.  Also,
you might try checking with restoration places like KAR Mustang
www.karmustang.com.   I figure if Coddington can have custom
windshields made for his custom rods, using a template made of poster
board (including the angles and curves), there should be something
available for the many fastbacks still out there.
