I literally just got done making new side windows for my Series 7.

Used a fine tooth bandsaw blade to cut them slightly oversize and then took down to the final size with a block and sandpaper.

Per the manual, the rivets are 1/8" by 1/4". Be sure to step up your holes to 5/32" (before pulling rivets) to reduce the possibility of cracks.

Leave the protective film on as long as possible to reduce the likelihood of scratches while doing all this.
