Installation
1. Assemble weatherstrip rubber to the opening with
weatherstrip retainer groove to inside of body mak­
ing sure the outer channel of weatherstrip is firmly
seated on edge of door panel all around the opening.
Watch this carefully on the corner radius. It is im­
portant to start the rubber at the top at the point
shown in Figure 74, going forward, down and around.
Cut off excess rubber about one-half to three-
quarters of an inch long. Butt the two ends together
and crowd excess rubber on. This makes tight joint
and prevents separation at joint after window is in
service.
2. Install the glass run channel inside the weatherstrip
rubber, starting half way up the rear side of open­
ing, coming down and around the opening to rear.
Cut off any excess channel at joint. Leave at least 6
inches of each end of channel out of rubber until rear
glass is in place (fig. 75).
The installation of this window is made
NOTE:
from the inside of the job with door in closed
position. The use of a mixture of liquid soap
and water or some other type rubber lubricant
applied to the rubber will make the installation
of this channel as well as the other filler sec­
tions much easier to install.
3. Set lower edge of sliding glass (front section) in run
channel with upper edge of glass back of joint in
