Looking for help. Need to replace lower radiator hose on a 1990 454ss. All the aftermarket ones are not shaped the way the old one is, thus they all dont fit properly. They dont have the proper bend where it goes around the fan shroud to connect to radiator. They all kink when I have tried to install. General Motors has discontinued the hose. Wondering if this is something others have fallen into and what maybe solutions. GM original part # was 15639031 then interchanged with # 15659614 Thanks
