I have had good luck finding soft top parts @ suzkicarparts.com.
Put the gasket on the new window. Put a small diameter rope or cord in the channel with a foot or two extra to pull on later. Put window in the opening on the outside of car. Have someone hold window firmly in place. Pull on the cord from inside the car and work the gasket into place. It helps to put powder or wd-40 on gasket to make it slip into place easier.
To replace the rear window in a 1994 Chevy Silverado you must first remove the old window. This can be done by removing the seal around the window and gently pulling the window out. Apply rubber sealer around the new window opening in the truck. Wrap a rope around the rubber sealer of the new window and position it in the window opening. Carefully remove the rope once the window is resting properly in position. As the rope is removed the rubber sealer should hold the window in position. Reapply the rubber seal if it is available for extra security. Allow the window to set for 10 minutes.
It is pressure-fitted into a rubber gasket and held by a flexible mastic substance.
Depending on the year & make of the vehicle it should be mounted in a rubber "gasket" which holds the glass in place. You need to put some sealer around the "gasket" before putting it on the cab opening channel. The glass should go in with a little soap around the edge by putting a small string in the "gasket" channel, then put the glass in the bottom of the channel & have someone pull the string while working the window. Pull the string from both ends at the same time causing the "gasket" to flip out over the edge of the glass.
THIS IS CALLED WINDOW GASKET TRIM
If there is a rubber gasket around the glass you sould be able to push it out and to replace get clothes line ro[e and run it in the in the middlemof the gasket all the way around have someone get inside while somebody pushes on the window start to pull the rope and the gasket should start over the lipo in side and follow it all the way around it should suck right in I have done a few of these good luck
Begin by removing the Geo Tracker door panel. The entire window mechanism will be visible. The window linkage will have adjustment nuts on each end of the linkage.
You put the seal on the glass then put the window in the frame. This eliminates the pressure on the glass. IT is easier to run a glazing tool around the metal frame without damage than it is to run it around the glass.
Window Rubber seal
You can get a window regulator for a 1993 Geo Tracker at auto part stores. You can also check with local salvage yards.
you will need two people for this job, go to an automotive sotre and get " gator wire" it has one sharp edge, poke a hole in the rubber gasket to feed the wire though and then go back and forth using the wire like a saw and it will cut the gasket and release the window.
