farther before it seals against the body post. If this
case exists insert one shim at the front of the front
track and test the door. If not enough add the second
shim. Two shims or 1/8" makes a considerable
change in door movement and should be sufficient in
most cases.
5. In cases where the door is not going out as far as it
should, be sure that the track is out as far as the
mounting brackets will allow.
6. After the adjustment on the front track is made close
the door and check the position of the rear roller on
the rear track. If roller is not centered on track,
adjust the track as required to correct.
7. If front door lock striker is too low, it will raise the
rear roller off the track when door is in locked posi­
tion. Raise striker slightly by striking it with ham­
mer to correct.
8. Letting the door travel out farther as it closes gives
tighter seal at the door lock post as mentioned in
paragraph 4.

COMPLETE DRIVER’S WINDOW
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 firm ly
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 95, going forward, down and around.
Cut off excess rubber about one-half to three-quar­
ters 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 serv­
ice.
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.
