Sure! So if you take a look at photos of the side/door of the car, you'll see and orange L-shaped piece that runs along the front and top of the door. It's about 1.5" wide all around. Here's what Don did:
1) Use the window as a template to cut out those orange L-shaped pieces in metal (not sure if steel or aluminum).
2) Cut about 3/4 to 1" of the window front and top edge off where it is underneath the newly cut mounts.
3) Powdercoat/paint orange. Obviously.
4) Attach the mounts with rivets using the trimmed pieces of 3/4 - 1" lexan as spacers between the body.
5) Now you can slide the window into the mounts. It does scratch it a little but it's not visible when the window is in the mounts.
6) The latch at the bottom is hard to describe without a picture, but it's located roughly in the middle of the lower edge on the inside of the window. It pushes onto the inside of the door, thus forcing the window onto the outside of the car when engaged. You can release it from the outside via a finger-sized hole.
The window seemed very snug. I hope this makes sense. I'll consider doing something like this once I'm looking at mounting windows after it's on the road.
