I am getting ready to get the heater hoses from the firewall to the pump. Its on an 73 Dart Sport. Are the sizes 5/8 and 1/2" hoses. I measured them and that is what I got but it seems like the pipes on the pump look the same size. just want to make sure. also where do we get the plate that covers the heater core tubes on the firewall side.thanks,Bill
