There I was minding my own business driving down the interstate in the 71, in the rain.Thats when the trouble started,a wet left ankle,water coming from under the dash,just left of the column.Took a quick look under there,nothing obvious.Never leaked inside before,any ideas where to start looking- thanks John

Could be water coming in from under the windshield, could also be a rotted out hole inside your cowl area.

yea, i would check the windsheild and the cowl. Any open holes in the firewall possibly?
