I'm removing the factory heating and air, and I'm left with three huge holes in the firewall. Is there a factory or reproduction delete plate to cover these, or is it break out the welder time? Another question is where does the water drain that falls into the cowl vents? The water looks like it just runs down the inside of the passenger kick plate and finds a way out between the body seams, is this correct? I could probably grab the garden hose and find out for myself, but the floor pan, and under the dash are stripped to bare metal, and I would rather find out the proper drainage path without the use of a garden hose.
