A common, but critical, part that generally needs to be replaced on a classic squarebody is the screen under the cowl panel. The screen helps to stop debris from making its way into the wiper area. Over time, these screens can become brittle and start coming apart which can allow debris through and keep water from draining out as it should. BROTHERS Trucks has the solution with their new replacement cowl panel screens for the C/K series pickups and Blazer/Jimmy/Suburban.
