another thing i found on a 66 i used to own was under the glove box in the cowl panel where the cab is welded together there is some black sealer put into this area and when it gets bad it will drip in a heavy rain while being driven.this area is behind the glovebox and dash.it is under the panel where wiper motor bolts in just about underneath the passenger wiper.i have owned 2 or 3 of these trucks that drips in this area.if it has been dripping for along time when you look up under there you may find some rust out where the sheetmetal has been spot welded together at the factory.hope this helps.
