When i wrecked my blazer the fan motor crushed the plenum and disfiguRed the little hole THAT THE AIR FLOWS THROUGH. I know i wont be able to get the firewall pulled out enough to put a new plenum thing so could i just make one and tack it on to my firewall where the old one was and seal around it. would i just build a box with a hole for the fan? or does it have to have a certain shape/ PLEASE HELP ITS REALLY COLD, THIS IS MY ONLY TRUCK AND I CANT AFFORD TO LEY A BODY SHOP FIX IT.
