Van-tilation options?

My 67 panel seems to be breezy up front with vents and windows open, but gets pretty warm for anyone setting in the back. What are some options for air circulation in the back?

do you have any roof vents of any kind in the rear? I have two small vents in mine. one at the front and one at the back. they are two direction vents. that means that they can open to the front or rear. I open the front one in the front, to draw air in. and the rear on towards the back, to let the air out. it makes a nice flow.
do your rear doors have windows? or is it a full panel? if there are windows, you could get some pop outs for them.

I do not have roof vents and my windows are fixed. I have read that pop out cause exhaust to come in while driving. Is that true?

,,,,you can tape some plastic bags to the ceiling and drive it with the front windows and vents open to get an idea of what the air flow is then bungee the side and rear doors open a little with a 2x4 stuck in them to see what the air flow and smell would be if you installed swing out windows or roof vents in there,,,,,just run some tests,,,,,see if things get better.......I used 12 volt oscillating fans on the walls to cool things down.........

Dodger, I have heard as well about the exhaust. But have to say I have been driving around for years with rear pop-outs and "never" had that issue. I do believe if you have your exhaust piped out the back is when you run into this problem. Mine ports in front of the rear wheel on the driver's side and have never had exhaust get sucked in.

Simply put, that hot air needs to be vented somehow......

Thanks for your ideas. I will give them a try. My exhaust exits in front of the rear tire on the drivers side as well.

I switched my rear door windows from fixed to popout, had no choice here in GA since its so dang hot. There is a very minor whiff of exhaust leaving from a dead stop but other than that I have no issues with exhuast coming inside.

Note however that I run side pipes so my exhaust is blowing out in front of the rear tires. If your pipes come right out the back you may have a problem.

If pop outs arent an option Ive seen small sun roofs cut in back there before and it seems like it would work.

You could always install some 12V fans, I see some adjustable, chrome ones on ebay that look pretty cool. Probably not as good as window open, but may do alot.

A vent/fan in the roof would be good too.

I have a window van and only open the side windows, have not tried opening the rear because I was worried about fumes, I would certainly try it if i had no side windows though.
