Hello All, I need to removal the complete dashboard in my B250. It seems to be connected at the windshield. I can feel the backside of screws in the cowl that could be holding the dash in, but I don't see the heads. Does the windshield have to be removed to remove the dash??? Also, I need a schematic of the air vacuum lines of the a/c, defrost & heat doors inside the dash. Damn rats got in it and chewed up the plastic lines. Thanks all!!!
