This is a pretty easy mod. Do one window at a time, as you may learn something and get better over time. It would be easier with a second person to help hold stuff, although I did it alone. Save your old window and weather stripping, it's valuable and you or a friend may need it later.


1) Carefully remove the hinged window from the donor van and save the screws

1B) Carefully remove the weather stripping from the donor van

2) Remove the fixed window from your van

3) Measure and mark where the holes go for the hinged window

4) Pre-drill 1/8" holes

5) Install weatherstripping

6) Install screws in widow hinge

7) Install screws in latch

8) Repeat until you've finished the project.

9) Enjoy your upgraded van!
