I have a 72 in need for some serious sheet metal repair. Problems is, I dont know how big my patch panels need to be. I question,"Do I really need to buy that $200 quater panel piece when the $60 one will be big enough?" Many stores offer full patch panels, half patch panels, and quater patch panels, but nobody really lists dimensions. If someone out there could point me in the right direction to determining these sizes (not just on quater panels, but all sheet metal pieces) Id greatly appreciate it
