I recently helped walk a fellow member through the install of some naca ducted Lexan triangle windows, and he suggested that I share the instructions here for others. So here's my guide to a relatively painless window swap procedure.
Here's a PDF file for easier saving/printing: Right-click, save as.
PHASE 1: REMOVAL
1. Remove the door cards.
2. Peel back the plastic splash shield material.
* CAUTION! This stuff can be very sticky and stretchy and can make a huge mess if you aren't careful.
3. Remove the screw at the top of the triangle window.
4. Roll down the door window.
5. Remove the three bolts (10mm) hold the door window onto the window regulator.
* Start with the one at the front and then do the two at the rear. You will probably have to roll the window upward slightly when going from front bolt to upper rear bolt to lower rear bolt.
6. Remove the two window stops at the top of the door (10mm).
7. Carefully slide the door window out of the door. Be careful not to tear any weatherstripping at the edges of the window.
8. Remove the two bolts (10mm) that hold the front window guide rail in place.
9. Slide the top corner of the triangle window weatherstripping off of the frame.
10. Remove the final screw holding the guide rail to the frame, and then wiggle guide rail away from frame.
11. Work the window out of the weatherstripping and remove from the frame.
* I find that it is easiest to work the top corner out first and slide the window backward away from the frame.
