I have a 66 c10 with the 283 I am looking for information on how these came from the factory regarding the top radiator hose. I have been told that these had a metal pipe for a radiator hose with rubber fittings on the radiator side and the thermostat side. If someone had a picture they could post here that would be helpful to me also. If in fact this was the way they came from the factory someone changed my top to an all rubber hose and discarded the original pipe. Are these pipes made aftermarket anymore? Thanks Chris
