On my non AC squares from the 70's, they had the vents down in the kickpanel that open by the park brake release, this 81 up cab have those? If you're hot and sweaty and doing 65 on the highway they will blow the hot right off you, 10x the cooling effect of a wing vent without all the wind noise in the ear. It will also let you know how much dust you have on the floor.
