Switch Hole Confusing
Dear Windy,

WRONG PLaCE!
There seems to be a confict between
t 55²³520²236²23²2
and
our Cobras.
Para
³3²³05
says that the rain removal thermal switch is installed
in an opening in the windshield. Fg
³3²³4
on Page
³3²30
shows the
opening
3
inches le±t o± Buttline
0´00´
We're con±used because on all o± our Cobras the pre-drilled hole
is right on Buttline
0´00´
When we install the switch, hot air ±roM the rain removal system
warps the windshield²
Can we ±ill in the pre³drIled opening and drill a new hole
3
inches
le±t o± Buttline
0´00,
like it shows in Fg
³3²³4?
