Tighten the rods tend to make the bow at the top of the cowl panel incease. The only way for that is if the cowl panel drops.??? Torque could pull it down as the rod pushes the fender connection forward that could force the back of the rod back toward the rear sucking that part of the cowl down. Repo metal is as heavy gauge as original and this cowl panel is repo part. .Just have to keep trying it.
