So one thing that kind of sucks about these old trucks is that there are no relief vents in the cab. You really have to wing the doors closed when the windows are rolled up. Time to fix that. The door jambs would be the perfect spot to install a pair of relief vents if we didn't have our rear speakers installed in the cab corners. That being the case, we decided to utilize the kickpanel vent openings as our path for air to escape the cab.

Clockwise from top left: We picked up a pair of stock kickpanel vents, and stripped them down to the bare housings. Sheetmetal from a York air conditioner was cut to create a back panel for each housing. The panels were welded into place and a pair of relief vents were fit up. These vents allow air to pass out of the cab, but do not allow air in. This should make a noticeable improvement in closing the doors with the windows up, without creating a draft. Since nobody wants to see the backside of the relief vents, and louvers are cool, louvered panels were made up for the interior side of the housings. Everything is ready to media-blast and paint.
