The cowl will be mounted back in the original location. It will be held in lace with screws so it can be removed anytime needed. Eventually, the ends of the cowl piece will be enclosed in a way for water to drain out. The entire vent box is sealed with seam sealer for a water tight area. I will cut holes in the back wall for heat/ac fresh air, and cab vents. There will be mounting brackets added to support the wiper pivots and the wiper motor. The original coupe's wiper post holes were welded closed.
