I have a 440 duster that I am using the stainless steel flex pipe with the polished ends and I am having big trouble sliding the bottom one on to the radiator 1-3/4 one I can get it high enough to put the clamp it just pops off. so I am thinking of going back to the regular stainless braided hose just want to get the correct part number. I am looking for lower but the upper as well so if anyone know the part numbers for dayco or goodyear that would help.
the shape of the hoses I am looking for look like this. i attached a picture of the hoses i am looking for

thanks
