glass is not tempered and edges are not sanded (rough cut) causing a tight fit. Used very little force and it cracked. Found a replacement that was tempered and sanded actually pounded on it to get it in and it looks great.

We are
truly sorry that the glass broke during installation. But please understand
that the glass, originally, was never tempered for the rear window of that
truck. Original rear glass was just plain old glass, and as a restoration parts
supplier, we have always strived to supply correct parts. Below is a bit of
interesting history on the evolution of safety glass in vehicles.

Laminated safety glass was first offered as
standard equipment on the 1936 Rickenbacker. ("Engineering Break¬throughs:
A Century's Worth of Better Ideas," Car G? Driver (Jan. 1988).) From 1936
to 1959, United States manufacturers used laminated safety glass in all windows
except the rear window. (Fargo, Windshield Glazing as an Injury Factor in
Automobile Accidents (1968).) In the late 50s and early 60s, car manufacturers
started looking for cheaper glass to use in the passenger windows. (Ibid.) By
the 1960s, American manufacturers had, for the most part, abandoned laminated
glass in favor of tempered glass. (Ibid.) To justify this change, the manufacturers
changed the ANSI glazing test methods so that tempered glass could pass the
tests. (Ibid.)
