For sure the new rear screen will not be plain glass that could break into
shards.   I believe all 3 litre Volvo powered cars that went to the USA had
glass rear screens.  I don't think the regulations here in USA allowed them
to be imported with plastic rear screens.

 

All the front screens I have ever bought were laminated glass not toughened.


 

Making a metal former to produce a rear window sounds like hard work!  We
usually make the former  from GRP by laying up inside an old screen.  It
really needs to be larger than the finished screen but that is not difficult
as the extra inch or so does not need to be so accurate. Just extend the old
screen with some strips of wax bought from your GRP supplier.

 

It is far simpler to take the former to somewhere that makes
Perspex/Plexiglass screens in volume. They will have an oven to heat the
sheet evenly and then it virtually just needs dropping over the former as
the bends are not that tight.  The former should be temporarily covered with
a piece of baize (same as billiard table skins). They will have this.  As
they buy the Perspex/Plexiglass  in volume usually it is cheaper to have
them do the whole job than it is to buy  a sheet of material.  Trying to
bend it with a heat gun sounds like a recipe for a wasted sheet of material
unless you are very lucky!
