What A/C are you going with? If it doesn't pull fresh air, are you worried about not having vents to open for fresh air when A/C running? I was reading some guys are having to open the passenger side vent for fresh air sometimes or they have issues.. I need to read more on what exactly they are experiencing...

Those speakers look great in there. Put any sound dampener behind them on the metal cowl? I hear blow back causes distortion and sound dampener directly behind the speaker stops that.

Looking good man! I'm taking notes
Vent windows are held together by rivets. To get the glass out, you drill out the pivot rivet and take the nut, spring, and washers off the bottom. Rivets get drilled out from the head side and use a punch to knock them out. I left the wing glass in the channel because we had so much trouble getting them back in on my dad's 64. So I taped off the glass and then blasted and no problems. In the video link (below), he sandblasts and paints the entire assembly but I don't see that as necessary as some of it is galvanized and mine were in good shape. The parts that were painted definitely needed paint though. The black channel with the chrome strike plate for the wing window latch can be pulled off the frame. I'll take pictures of the parts in their painted form this weekend before we reassemble.
Here's a link to a good video I've been watching on vent window restoration: https://www.youtube.com/watch?v=WiZOiHmcb_w

I plan on going with the Vintage Air Surefit system. It was my understanding that these systems reuse the air in the cab since there's no fresh air intake anywhere. I saw a picture where the right side of the blower assembly was almost up tight against the kick panel sheet metal, whereas the outside of my speaker grille is probably 1.5" or 2" out, so hopefully that doesn't become an issue. Maybe the lines coming out of the box end up in a different spot than intended and hopefully that's not an issue.

I didn't put any sound dampening behind the kick panel speakers. They're pretty low power speakers so hopefully it won't be noticeable if there is some distortion. It's going to be hard to hear the music over the sound of those black widows anyway....
