Thanks, windguy.
Thanks, jrm223.
The window is frameless itself but does have the metal door frame around the window inside. An inside screen and magnets could work I'll give that some thought, thanks.
You can now get a full set, front row, second row, third row and back glass (lift gate or doors) from HeatShield. They only have the third row set for long wheel base. Go to their website and enter your model information. These are tops not only for shade but for heat deflection, and they hold up way better than any I've ever tried.

@stanger_missle - Don't think you're overthinking this at all. You're just exploring the what ifs, which is cool. I too have a cargo van with only two speakers in the front doors. Below is a pic of the slider doors speaker mounts you're referring to. Your concerns about road noise are valid. I personally wouldn't bother mounting speakers there. I think that mounting point would be good if you had passengers in this area but it would be a waste otherwise. If you want music for the cab area, then that's where I'd add or upgrade speakers for better sound. If I spent more time in the van I would consider an audio upgrade. Good luck!
I bought a 3 piece set (windshield and both front side windows) for my Jeep Wrangler from Heatshield. I got the gold color but these fit great and were very well made. The TC has such a huge windshield that a sunshade is a necessity. I see that they make shades for the back door (both styles) and the front side windows for the TC. My van turns into an oven here in Florida.
