was your cab AC before?
did you hook up the pass side vent to it?
or hood to cab seal?
how is the area down the sides of the cab
below the name badge area,but under the fender
a friends dad put his shop vac sucking out of the otherwise sealed up car,
used insence along the firewall,couldnt see a leak under the wiper motor,but saw smoke from inside
