Rear bulkhead fire containment


We’re looking to clean up the rear of our race car, specifically to make a more robust and hole free bulkhead to the trunk in order to contain fire/fuel. Does anyone make a rear bulkhead panel in steel, or have a template from a past project they could spare? Just trying to save some time and effort of pulling the rear lexan and navigating around the cage for rough fitment and templating. Thanks!
