My car has a few of these original screw style clamps but this is the last one intact, is there a source for these-I'd like to get 7 of them for the radiator to tank hose and the fuel lines to the 3 webers. They are 2 piece, the band and screw, plus a separate curved plate that fits between the hose and screw. If possible I'd do the coolant hoses too but I haven't seen these anywhere in any size. Thanks.
