Original upper radiator hose - molded or flex?

[motoMark]

It's time to replace the upper radiator hose on my 51 Cambridge and NAPA is showing both a formed hose and a flex hose. The hose I have on there now is a flex hose, and have no idea how long it's been on the car. Does anyone know what type of hose these cars originally came with?

Molded

go with the molded and leave the generic ribbed flex hose for the Ferd and Chebbie boys......much nicer look....
